Fluid-Structure Interaction Analysis of a Piezoelectric Cantilever for Energy Harvesting

A numerical investigation was conducted to study the impact of varying the velocity magnitude and the elasticity of the cantilever on the performance of the piezoelectric beam such as tip deflection and voltage, tip electric field and maximum electric field. COMSOL software was used to solve for the governing equations taking into account fluid-structure interaction. The results of this investigation were compared against analytical results found in the literature and the agreement was excellent. The results presented in this study demonstrated a substantial impact of the flow velocity magnitude and elasticity of the cantilever on the tip deflection and voltage as well as maximum electric field. As the velocity increased and the elasticity of the microcantilever decreased, the tip deflection increased and consequently increased voltage and electric field. This study suggests that high voltage and electricity can be generated from energy harvester if they are subjected to high fluctuations.

Patient-Specific Characterization of Breast Cancer Hemodynamics Using Image-Guided Computational Fluid Dynamics.

The overall goal of this study is to employ quantitative magnetic resonance imaging (MRI) data to constrain a patient-specific, computational fluid dynamics (CFD) model of blood flow and interstitial transport in breast cancer. We develop image processing methodologies to generate tumor-related vasculature-interstitium geometry and realistic material properties, using dynamic contrast enhanced MRI (DCE-MRI) and diffusion weighted MRI (DW-MRI) data. These data are used to constrain CFD simulations for determining the tumor-associated blood supply and interstitial transport characteristics unique to each patient. We then perform a proof-of-principle statistical comparison between these hemodynamic characteristics in 11 malignant and 5 benign lesions from 12 patients. Significant differences between groups (i.e., malignant versus benign) were observed for the median of tumor-associated interstitial flow velocity ( P = 0.028 ), and the ranges of tumor-associated blood pressure (P = 0.016) and vascular extraction rate (P = 0.040). The implication is that malignant lesions tend to have larger magnitude of interstitial flow velocity, and higher heterogeneity in blood pressure and vascular extraction rate. Multivariable logistic models based on combinations of these hemodynamic data achieved excellent differentiation between malignant and benign lesions with an area under the receiver operator characteristic curve of 1.0, sensitivity of 1.0, and specificity of 1.0. This image-based model system is a fundamentally new way to map flow and pressure fields related to breast tumors using only non-invasive, clinically available imaging data and established laws of fluid mechanics. Furthermore, the results provide preliminary evidence for this methodology's utility for the quantitative characterization of breast cancer.

Experimental and Numerical Investigation of Tip Leakage Flows in a Roots Blower

Computational fluid dynamics (CFD) can help in understanding the nature of leakage flow phenomena inside the rotary positive displacement machines (PDMs). However, due to the lack of experimental results, the analysis of leakage flows in rotary PDMs by CFD has not yet been fully validated. Particle image velocimetry (PIV) tests with a microscopic lens and phase-lock were conducted to obtain the velocity field around the tip gap in an optical Roots blower. The three-dimensional unsteady CFD model of the Roots blower with the dynamic grids generated by Screw Compressor Rotor Grid Generation (SCORG) was established to predict the gap flow under the same operating conditions. The images obtained by the PIV tests were analyzed and some factors which compromise the quality of test results in the gap flow were identified, such as reflections and transparency of the window. The flow fields obtained by CFD have the same flow pattern and velocity magnitude as the experimental results in the majority of observed regions but overestimate the leakage flow velocity. The CFD results show a vortex induced by the leakage flow in the downstream region of the gap. The flow losses in the tip gap mainly happen at the entrance upstream of the gap. Finally, some suggestions for future work are discussed.

Development of thermal bridge numerical model, based on conjugate heat transfer and indoor and outdoor environment parameters

The presented study reveals the development of a 3D numerical model for thermal bridge assessment, based on conjugate heat transfer and CFD methods. With the developed model, thermal simulations are performed, in order to analyse the interaction between different ambient conditions and material properties. The results show that the wall boundary layer profiles are depended on the attached air flow velocity magnitude and implemented wall roughness. The parametric analysis, of the varying ambient air temperatures, confirm the linear dependence to the internal wall surface temperatures. The demonstrated correlations, in regard of the attached air flow velocity magnitude and wall roughness heights, are non-linear. The most characteristic result, achieved in the simulation study, is the impact of the wall roughness, over the internal wall temperature. The increase of the roughness leads to significant increase of the internal wall temperature. Explanation may be found in the boundary layer flow velocity magnitude near the external wall, which decreases the heat energy transfer between the solid and cold fluid medias.

Surface Roughness Effects on Molecular Gas Lubrication

The effects of surface roughness on the molecular gas lubrication characteristics have been studied for defining the application limit of Molecular gas film lubrication (MGL) equation against roughness. The applicability has been evaluated by comparing the difference of characteristics calculated by MGL equation and direct simulation Monte Carlo (DSMC) method. In this paper, the evaluation for the two kinds of gas film, the one of which has sinusoidal surface roughness and the other has triangular surface roughness, is presented to check the influence of roughness shape. It comes evident that the magnitude of transverse flow velocity has close relationship with the slope of surface roughness, by comparing the flow pattern of two roughness shapes. The transverse flow, which is not included in MGL equation, causes the difference between the results obtained by MGL equation and DSMC methods and, thus, can be the index of applicability of MGL equation. After all, the causality between the transverse flow and the roughness slope is clarified and their influence to the applicability of MGL equation is confirmed.

Magnitude and Direction of Groundwater Seepage Velocity in Different Soil and Rock Materials

To understand and anticipate flow in various groundwater media, the magnitude and direction of groundwater flow velocity must be deemed. The studied area which is called Halabja-Sadiq Basin is in the northeastern part of Iraq and covers an area of approximately 128,000 square hectometers. There are several groundwater aquifers in this region that supply nearly over 90% of all water needs. Subsequently, it is of highly requirement to identify various groundwater behaviors in the area. The objective of this study is to estimate the magnitude and direction of the groundwater seepage velocity with the aid of groundwater tool in Geographic Information System technology. Refer to the results of this analysis, the magnitude value of groundwater flow velocity ranged from 0 to 51 m/d, whilst the general flow movement is from the eastern part to the western part of the study area. The factor governing the direction of flow and velocity magnitude indicates the direction of dipping of the geological formation strata, the high head of groundwater in the eastern part, and the low transmissivity properties of aquifer materials in the western part.

Numerical simulation of static and dynamic stability of air-bubbles in highly flowable cement-based materials

A computational fluid dynamics (CFD) software and image analysis technique were used to simulate the flow performance and stability characteristics of air-void system (AVS) of fresh highly flowable cement-based materials as a three-phases gas-liquid-solid system using a coaxial cylinders tribometer set-up. The investigated characteristics consist of flow velocity, shear rate, and pressure magnitudes of the suspensions, as well as displacement, elongation, orientation angle, and rising velocity of the air bubbles in both parallel and perpendicular planes to flow directions. Static and dynamic shear modes as well as different shearing zones were evaluated. Different suspending fluids having different plastic viscosity and surface tension values varying between 5 and 30 Pa.s and 5 and 73 mN/m, respectively, were investigated. The suspensions consisted of spherical solid particles of 2.5, 4, and 5 mm diameter with 3.8 % volumetric content, as well as 18 and 150 air bubbles of 2- and 1-mm diameter, respectively, corresponding to 7 % volumetric content.According to the numerical results, the shearing mode and distance from the shearing source were shown to be the most dominant parameters affecting the flow performance and stability of air-void system in highly flowable cement-based materials, compared to the suspending fluid characteristics. Moreover, both the diameter and initial vertical positions of the air bubbles can significantly affect their stability characteristics.

Dancing with the Cells: Acoustic Microflows Generated by Oscillating Cells.

The interaction of a sound or ultrasound wave with an elastic object, such as a microbubble, can give rise to a steady-state microstreaming flow in its surrounding liquid. Many microfluidic strategies for cell and particle manipulation, and analyte mixing, are based on this type of flow. In addition, there are reports that acoustic streaming can be generated in biological systems, for instance, in a mammalian inner ear. Here, new observations are reported that individual cells are able to induce microstreaming flow, when they are excited by controlled acoustic waves in vitro. Single adherent cells are exposed to an acoustic field inside a microfluidic device. The cell-induced microstreaming is then investigated by monitoring flow tracers around the cell, while the structure and extracellular environment of the cell are altered using different chemicals. The observations suggest that the maximum streaming flow induced by an MDA-MB-231 breast cancer cell can reach velocities on the order of mm s-1 , and this maximum velocity is primarily governed by the overall cell stiffness. Therefore, such cell-induced microstreaming measurements, including flow pattern and velocity magnitude, may be used as label-free proxies of cellular mechanical properties, such as stiffness.

A study on the optimal arrangement of tube bundle for the performance enhancement of a steam turbine surface condenser

A porous medium model was used for numerical and experimental investigations of a system that includes a tube bundle inside a steam turbine surface condenser. A condensation model was developed to predict the condenser performance using user-defined functions (UDFs) in the commercial computational fluid dynamics software FLUENT. The shell-side pressure drop around the tube bundle is an important indicator for the condenser performance and can be used to compare different condenser-tube arrangements. The condenser performance was analyzed using various numerical results, such as the absolute pressure, condensation mass flow rate, velocity magnitude, and air mass fraction. Detailed effects of the various parameters of tube bundle are discussed. These parameters had a great influence on the condenser performance. The numerical data were generally in good agreement with those obtained by experiments. An important practical finding from this study is that changing tube bundle can significantly improve the condenser performance by reducing the shell-side pressure drop. Consequently, the optimized model has approximately 40% better pressure drop performance than the base model, and the numerical results were verified with the experiments established by Donghwa Entec.

Three-dimensional mesoscopic permeability of porous asphalt mixture

This study aims to accurately analyze the three-dimensional (3-D) mesoscopic permeability of porous asphalt mixture. Industrial CT scanning and 3-D image reconstruction technology were used to analyze the mesoscopic void space in porous asphalt mixture. A mesoscopic permeability numerical model was built based on the Lattice Boltzmann Method (LBM). The vertical permeability of porous asphalt mixture was analyzed with the numerical model and verified by a self-designed permeability coefficient tester that can apply a confining pressure to the specimen side using a rubber membrane. Results indicate that the self-designed permeability tester has a rigorous test theory, simple operation, and reliable results. Results also illustrate the uniformity between the test and numerical model calculations. By applying different boundary conditions, the magnitude and distribution of permeability flow velocity at any point within the porous asphalt mixture sample can be accurately obtained. The principal and deviator vector of the macroscopic permeability coefficient can be acquired. The 3-D mesoscopic permeability was found to strongly correlate with the mesoscopic void structure. The transverse permeability coefficient is about 1.5–2.0 times the vertical permeability coefficient. Samples in different orientations or with different heights had a variable permeability coefficient. The larger the sample’s height, the smaller the permeability coefficient. The findings of this study are expected to provide more precise 3-D permeability parameters for drainage system design using asphalt pavement and satisfy the requirements of drainage function and traffic safety.

Effect of siphon flow on resonant damping of kink oscillations in magnetic flux tubes

The effect of siphon flow on kink oscillations of magnetic flux tubes is studied in the thin tube and thin boundary layer (TTTB) approximation. The presence of a transitional layer results in oscillation damping due to resonance absorption. To calculate the damping rate we use the regular perturbation method with the ratio of transitional layer thickness to tube radius as a small parameter. We found a dependence of the ratio of decrement to the oscillation frequency, γ/ω1, on the ratio, χ, of flow velocity magnitude to the Alfvén speed in the tube core. The general theoretical results are applied to a particular case where the density radial dependence in the transitional layer is linear. We consider two models. In the first model, the radial dependence of the velocity amplitude is such that the resonance in the transitional layer occurs where the flow velocity is zero. In the second model, the flow velocity is non-zero in the whole transitional layer. In both cases, γ/ω1 is an increasing function of χ. In the first case, the presence of flow can lead to an increase in γ/ω1 by more than a factor of two. In the second model, we only carry out the calculation in the case where the plasma density inside the tube is much larger than the density of the surrounding plasma. In this model, the effect of flow is less pronounced than in the first model, and the presence of flow can increase γ/ω1 by a factor of 0.25 at most. We discuss the application of the obtained results to coronal and prominence seismology. We conclude that while for typical values of velocity in coronal loops the effect of flow is weak, it can be quite substantial in prominence seismology.

Effect of seepage flow on incipient motion of sand particles in a bed subjected to surface flow

Understanding the interaction of the groundwater seepage flow and sediment transport along permeable boundaries is essential for managing soil beds and bank erosion. A significant bank failure may occur due to sediment transport under the boiling condition. In the present study, an experiment is conducted to investigate the effects of injection or upward seepage on the critical shear stress of a cohesionless soil bed subjected to surface flow. The upward seepage force acting on the soil bed particles may reduce the virtual weight of the particles. In turn, it may also reduce the critical shear stress acting on the particles. A theoretical analysis examines how the upward seepage force acts to modify the critical shear stress for the sediment entrainment due to the increase in the hydraulic gradient of the seepage flow. A force analysis reveals that the ratio of the critical shear stress with seepage to that without seepage is dependent on the ratio of the hydraulic gradient of seepage to its value at the quicksand condition. A test apparatus was built, and the effects of injection on the critical shear stress of cohesionless soil bed particles were measured. An acrylic channel with a rectangular cross section was prepared, and a section of a cohesionless soil bed subjected to an upward seepage flow was installed at the bottom of the channel. The experiment demonstrates that the induced seepage affects the dynamics of the channel flow, even though the magnitude of the seepage flow velocity is significantly smaller than that of the free surface water flow. The test results show that the dimensionless critical shear stress of the cohesionless soil bed particles decreases slightly as the hydraulic gradient of the seepage flow is increased when critical shear stress is determined at the upstream edge of the seepage zone. Furthermore, the dimensionless critical shear stress decreases sharply with the increment of the hydraulic gradient of the seepage flow when critical shear stress is determined in the seepage zone. However, it does not decrease in either case, as was theoretically assumed, even when the hydraulic gradient approaches to the critical hydraulic gradient or the quicksand condition.

The Flow Noise Calculation for an Axisymmetric Body in a Complex Underwater Environment

The flow noise of a sonar platform is one of the main background interferences for sonar applications. This paper focuses on the flow noise of an axisymmetric body in a complex oceanic environment. Under the condition of a constant stream velocity which comes from the axial direction, an analytical method for computing the flow noise power spectrum in the transition region of the axisymmetric body is given in detail. The flow noise power spectrum computed by the analytical method is in agreement with the numerical simulation result. Then the flow noise physical features of the axisymmetric body in different incoming stream directions and velocity states caused by the complex oceanic environment are computed and analyzed by the numerical method. The results show that as the incoming stream direction changes, the transition region will migrate and the flow noise radiation direction of the axisymmetric body will also rotate at an angle which equals the stream direction variation. The flow noise energy generated by other directional incoming streams is slightly larger than that generated by the stream coming from an axial direction. When the incoming stream velocity is time-varying, the vorticity change on the axisymmetric body surface is obviously stronger than that under a constant stream, and the generated flow noise energy is also significantly larger. In addition, it indicates that there is a significant correlation between the intensity of flow noise energy and the magnitude of flow velocity.

Performance of characteristic numerical boundary conditions for mixed convective flows past a heated square cylinder using a non-Boussinesq approach

This work represents an investigation of the performance of characteristic numerical boundary conditions on the unconfined 2D mixed convective flow of air past a heated square cylinder governed by a non-Boussinesq flow model. The working fluid (air) is taken to be thermally perfect with variable thermo-physical and transport properties. The fully compressible Navier-Stokes equations are transformed using body-fitted coordinates and solved using particle velocity upwind (PVU-M+) scheme on a structured O-type grid. To investigate the performance of characteristic numerical boundary conditions, the gravity aligned upward flow past a heated square cylinder at (α = 0°, M = 0.1 and 0.2, Re = 100, Fr = 0.5 and 1.0, Pr = 0.71, γ = 1.4, and ε = 0.07 and 1.0) is considered. The overheat ratio (ε) is defined as (Tw – T∞)/T∞, where Tw and T∞ are the uniform cylinder and free stream temperatures, respectively. In order to determine the proper choice of boundary conditions to be imposed on the far boundary, algebraic characteristic boundary conditions of Euler equations (AECBC) are considered in a local 1D sense normal to the far boundary. In this work, two sets of algebraic characteristic boundary conditions are considered. In one set (BC Set I), AECBC is used over the entire far boundary. While in the other set (BC Set II), AECBC is used over a portion of far boundary, that is characterized by normal flow velocity magnitude in excess of a threshold value, and entropy preserving extrapolating conditions for pressure and density over the remaining portion of the far boundary. It is shown that BC Set I generates spurious wave reflections and numerical noise from the far boundary, whereas BC Set II eliminates these numerical artifacts and captures the flow physics far more accurately.

Turbulent Kinetic Energy in Bolt Fishway

The paper presents an analysis the spatial distribution of turbulent kinetic energy (TKE) for bolt fishways, including the impact of additional spillway slots and fixed channel development. The research was done for two models, each containing a different arrangement of slots. The presented results of research for bolt fishways were obtained as an effect of laboratory tests. The measurements were done for three components of instant flow velocity magnitude (speed). Analysis of the results was done for a 3D flow structure using Matlab software. In the case of bolt fishways, significant differences were noted for the method of velocity and TKE distribution, in reference to research comprising channels with biological development. It was stated that a reason for this is the flexible development of the channel. The occurrence of extreme TKE values in the chamber (pool) is strictly associated with the characteristics of interaction zones between various flow structures. It was also stated that the lower the parapet of the slot’s spillway shelf is in the fishway’s partition, the higher TKE could be expected just downstream of the section. These establishments may be important for the designing process in the case of fish passes of various types of construction.

Image-Based Flow Simulations of Pre- and Post-left Atrial Appendage Closure in the Left Atrium.

For patients with atrial fibrillation, the left atrial appendage (LAA) is often the site of thrombus formation due to low atrial ejection fraction that triggers strokes and other thromboembolic events. Recently introduced percutaneous LAA occlusion procedure is known to reduce LAA-induced strokes. Despite having the procedure, there are still 11% of the patients who continue to suffer from future strokes or transient ischemic attacks, not accounting for the procedural related complications. The high failure rate is largely due to the variabilities in LAA's shape, size, and contractility which may result in ineffectiveness of this procedure. To correctly identify the candidates and evaluate the effectiveness of the procedure, we rely on patient-specific CT scans which provides the exact LA and LAA geometries and predictive hemodynamic analysis to assist in evaluating quantitative flow parameters pre- and post-LAA occlusion procedures. Hemodynamic parameters are critical to predict adverse hemodynamic flow patterns in LAA as well as the effectiveness of LAA closure in individual patient. The aim of this paper is to establish an image-based patient-specific computational fluid dynamic (CFD) simulation framework specific to the prediction of treatment outcomes of LAA closure with atrial fibrillation. This framework utilizes automated LA/LAA image segmentation which yields significant reduction in image processing. One set of patient data with successful procedure outcome is used to illustrate the potential of the proposed framework. The proposed LAA occlusion simulation framework is composed of several components: (1) a novel image segmentation procedure, which is fully-automated to identify LA/LAA geometries from CT images, (2) a finite-element mesh generation procedure which transforms the surface geometry into a 3-D volume mesh and properly identified boundary planes, (3) performing CFD simulations with atrial fibrillation flow boundary conditions, and (4) analyzing flow characteristics (velocity, flow patterns, streamlines, vortices) within the LA for before and after LAA closure. Based on the LA/LAA segmentation of a 65 year old female patient with chronic atrial fibrillation, a CFD analysis was pursued to examine flow characteristics upon LAA closure. The results showed that the flow velocity magnitudes were significantly reduced by a maximum factor of 2.21, flow streamlines were greatly stabilized, and mitral outflow appeared to be more organized. Vortices were dramatically reduced in size, number, intensity, as well as duration. During diastole, the peak vortex diameter was reduced from 2.8 to 1.5 cm, while the vortex duration was reduced from 0.210 to 0.135 s. These flow characteristics all indicated a reduced risk in future thrombus formation and strokes based on the established relationship between flow and thrombus formation. For the patient case under study, the effectiveness of the procedure is predicted and found to be consistent with the actual procedural outcome. This framework successfully predicted patient-specific outcome of a LAA closure procedure for one patient with atrial fibrillation. It can be further developed into a useful tool for pre-procedural planning and candidate selection. More patient data are necessary for further validation studies.

One- versus two-degree-of-freedom vortex-induced vibrations of a circular cylinder at [formula omitted

The one- versus two-degree-of-freedom vortex-induced vibrations of a circular cylinder are investigated on the basis of direct numerical simulation results. The Reynolds number, based on the oncoming flow velocity and cylinder diameter, is set to 3900. Three cases are examined: the elastically mounted body is free to oscillate either in the direction aligned with the current (in-line direction; IL case), in the direction normal to the current (cross-flow direction; CF case), or in both directions (IL+CF case). In each case, the behavior of the flow–structure system is studied over a range of values of the reduced velocity (inverse of the oscillator natural frequency). The in-line and cross-flow responses observed in the IL+CF case substantially differ from their one-degree-of-freedom counterparts, especially in the intermediate reduced velocity region. In this region, no vibrations develop in the IL case and in-line oscillations only occur if cross-flow motion is allowed. These in-line oscillations are accompanied by a major increase of the cross-flow responses, compared to the CF case. The two-degree-of-freedom vibrations are associated with the emergence of large-amplitude higher harmonics in the fluid force spectra. These aspects and more specifically the impact of the existence of a degree-of-freedom and oscillations in a given direction, on the fluid force and structural response in the perpendicular direction, do not seem to be systematically connected to changes in wake topology. Here, they are discussed in light of the orientation and magnitude of the instantaneous flow velocity seen by the moving body.

Mercury dynamic simulation of Minamata Bay by using a three-dimensional numerical model

Residual mercury dynamic has been the research emphasis since mercury contamination was publicly recognized in Minamata Bay. Simulation of mercury distribution and transport pattern is performed based on an integrated three-dimensional numerical model. Simulated dissolved total mercury and dissolved methyl-mercury show acceptable agreements with measurements. Deviation occurs during the simulation of particulate mercury at bottom layer and is probably caused by the existence of coarser sediments which could barely suspend to upper layers. Mercury transport pattern in larger Yatsushiro Sea is simulated and analyzed with mercury source from Minamata Bay. Study results suggest that substantial mercury deposition happened during preliminary stage of simulation. Due to the effect of current outside bay mouth, transport of mercury at middle and bottom layers has the trend to north, while west transportation of mercury output is presumed to happen during slack tide. Surface mercury transport is sensible to wind effect, moreover, higher magnitude of flow velocity causes different transport tendency compared with lower layers.

Numerical investigation of laminar compressible natural convection flow in asymmetrically and isothermally heated open-ended inclined channel

This study presents a numerical investigation of laminar compressible natural convection flow induced under high-temperature difference in an open-ended inclined parallel-walled channel heated isothermally and asymmetrically at the top wall (hot plate facing downwards) while the lower plate is considered adiabatic. The investigation is carried out with air (Pr=0.72) as the working fluid for a temperature difference of 110 °C from the ambient, over of range of modified Rayleigh number 6.2×101 to 1.6×104 and inclination of channel varying between 10 and 90° with respect to horizontal position. For the simulation, compressible governing equations without Boussinesq approximation is solved by employing new modified all-speed Roe scheme with matching preconditioning method, dual time-stepping technique and utilizing the modified Local One-dimensional Inviscid (LODI) relations suitable for compressible natural convection flow as non-reflecting boundary conditions at the inlet and outlet of the channel. Average Nusselt number based on inter-plate spacing increases with the increase of modified Rayleigh number and also with the increase of inclination from the horizontal position. This increase in average Nusselt number can be described by the variation of the level of thermal saturation inside the channel. Significant reduction in average Nusselt number is observed in the combined zone of lower angle of inclination and lower modified Rayleigh number. Visualization of fluid flow (temperature contour and velocity magnitude contour) indicates the existence of both fully developed flow and developing flow regime within the span of investigated modified Rayleigh number. Based on the investigation, a composite correlation between average Nusselt number and product of modified Rayleigh number and the sine of the angle of inclination considering as a single parameter is presented which can be conveniently used for designing of engineering application dealing with natural convection heat transfer under high-temperature difference.

Characterization of Single and Multiphase Hydrodynamics in Continuous Slab Casting Mold in the Presence of Applied Magnetic Field

A numerical investigation has been carried out to characterize both single and multiphase hydrodynamics in a continuous casting mold under the influence of a superimposed magnetic field. Three-dimensional single- and two-phase magnetohydrodynamic flow and turbulence models have been developed for numerical simulation. The computational model results are in agreement with the plant experimental measurements. In a single phase paradigm, with a functional variation in applied magnetic field distributions, the results have been shown for both conducting and non-conducting media. On the other hand, for multiphase flow, based on the actual magnetic field measurement values at the plant, simulations have been carried out at a representative 6 L/min argon flow rate. Overall, the superimposed magnetic field is observed to subdue the flow velocity magnitude and the distribution of turbulence intensity in the continuous casting mold. A similar phenomenon has also been noticed for multiphase flows.
