On the effects of reactant stratification and wall curvature in non-premixed rotating detonation combustors

The optimization of non-premixed rotating detonation combustors (RDCs) requires improved understanding of the coupled effects of reactant stratification, fluid property gradients, and complex shock-wave interactions on the detonation wave structure within annular geometries. In the current work, simultaneous orthogonal views of chemiluminescence and hydroxyl planar laser-induced fluorescence (PLIF) are utilized to establish the existence of a dual-wave system characterized by leading and trailing detonation waves that are closely coupled by the local flow physics. These features are persistent over a wide range of mass flow rates and are consistent with prior observations of non-premixed rotating detonations in annular geometries. The detailed instantaneous time sequences are compared with a 3D reactive unsteady Reynolds averaged Navier-Stokes (URANS) simulation to more clearly elucidate the in-situ combustion dynamics and the sensitivity to reactant inlet conditions. It is found that the dual-wave system results from unburned reactants that survive the leading detonation wave in the injector near field and are consumed within a trailing azimuthal reflected-shock combustion (ARSC) zone. By contrast, the injector far field is characterized by rapid mixing due to a sudden drop to subsonic conditions, and the bifurcated detonation wave structure collapses into a stronger, single-wave detonation front with higher overall pressure ratio as compared with the dual-wave system. While each RDC will have different inflow, mixing, and combustion characteristics, the underlying interactions between the stratified reactants and azimuthal wave dynamics identified through the combination of advanced MHz-rate diagnostics and 3D numerical simulations have important implications for the study of detonation wave stability, mode transition, and combustion efficiency in non-premixed annular RDCs.

CFD investigation of flow reversal in inverted U-tube steam generator under two-phase natural circulation

In this paper, a critical mass flow rate (CMFR) has been obtained for three different steam generators (i.e. two marine-type and one commercial) at different inlet void fractions using the CFD method to study the sustainability of natural circulation (NC) due to depressurization in two-phase NC mode. Because of depressurization, the transients in the inlet void fraction have been considered as multiple steady-state inputs, and the range of safe operating mass flow rate has been obtained. The results show that the characteristics curves shift with inlet void fraction thus limiting the operating mass flow rate range between 0.046 kg/s to 0.050 kg/s for M_SG1 and 0.051 kg/s to 0.055 kg/s for M_SG2. The effect of pipe roughness on CMFR has also been studied. The results can be used for the optimized design of the U-tube steam generator (UTSG) that will safely perform the heat removal operation during a small break loss of coolant accident (SBLOCA).

Development of a high-fidelity partitioned Fluid–Structure Interaction model of an Omega-shaped Coriolis Mass Meter and comparison with experimental data

Coriolis Mass Meters (CMMs11Such measurement devices are usually regarded as either Coriolis Mass Flow-meter (CMF) or Coriolis Flow-meter (CFM) or Coriolis Mass Meter (CMM). In this work, the latter naming is used.) are devices for measuring the mass flow rate of a flow in a pipe by a mechanism based on exciting a specific mode shape of the flow-meter’s structure and analyzing the system’s response to the interaction between the vibrating CMM’s structure and the flow. This interaction manifests itself as a phase-shift between the signals captured by the motion detection sensors, located on the CMM’s structure. By design, a characteristic of the CMMs is the linear relation between the induced phase-shift and the mass flow rate in a wide range of flow regimes. Due to the complexity of such dynamic systems, low-fidelity numerical models are often not capable of capturing the relevant physics and, therefore, cannot be relied on in the design process of the CMMs. The goal of this paper is to develop a physically significant and reliable high-fidelity Fluid–Structure Interaction (FSI) model of Omega-shaped CMMs which can be used in the virtual design scenarios. Such a model is useful for e.g. parametric studies and importance rating of parameters. In order to achieve that goal, different modeling aspects, simulation and post-processing techniques are systematically assessed. The result is a numerical model based on strongly coupled partitioned FSI between the CMM’s structure and the fluid passing through it. Both fluid and structural domains are discretized using finite element method (FEM). The induced phase-shift due to FSI is calculated for a range of mass flow rates. It is verified that the calculated phase-shift from the simulations varies linearly with the mass flow rate. Furthermore, the numerical results are compared to and are in good agreement with experimental results. Hence, the developed high-fidelity model is shown to be accurate enough to be used for designing and enhancing the performance of Omega-shaped CMMs, affirming the relevance of the thoroughly discussed modeling aspects.

Development and Use of a Residence Time Distribution (RTD) Model Control Strategy for a Continuous Manufacturing Drug Product Pharmaceutical Process.

Residence-time-distribution (RTD)-based models are key to understanding the mixing dynamics of continuous manufacturing systems. Such models can allow for material traceability throughout the process and can provide the ability for removal of non-conforming material from the finished product. These models have been implemented in continuous pharmaceutical manufacturing mainly for monitoring purposes, not as an integral part of the control strategy and in-process specifications. This paper discusses the steps taken to develop an RTD model design space and how the model was statistically incorporated into the product’s control strategy. To develop the model, experiments were conducted at a range of blender impeller speeds and total system mass flow rates. RTD parameters were optimized for each condition tested using a tank-in-series-type model with a delay. Using the experimental RTD parameters, an equation was derived relating the mean residence time to the operating conditions (i.e., blender impeller speed and mass flow rate). The RTD parameters were used in combination with real-time upstream process data to predict downstream API concentration, where these predictions allowed validation across the entire operating range of the process by comparison to measured tablet assay. The standard in-process control limits for the product were statistically tightened using the validation acceptance criteria. Ultimately, this model and strategy were accepted by regulatory authorities.

Heat transfer and pressure loss performances for additively manufactured pin fin arrays in annular channels

Additive manufacturing technology with metal powder has facilitated the production of innovative and even more complex heat sinks. The layer-additive process offers a wide range of geometries that may be exploited for advanced cooling purposes and the final identification of the best heat sink configuration has to deal with other constraints imposed by the specific application. This contribution focuses on the thermal and fluid dynamic characterization of water cooling annular channels for applications in internal combustion engine components, where also the load-bearing capacity is requested together with the cooling performances. The heat transfer inside the annular channel was enhanced by pin fins arrays that were manufactured by selective laser melting technology in AISI 316L stainless steel. Four pin fins arrays that differ in dimensions and geometries were experimentally tested over a range of mass flow rates to compare their pressure losses and heat transfer performances against those of the smooth annular channel. Furthermore, the test coupons were analysed through optical non-destructive techniques to characterize their geometrical morphology in terms of conformity with the designed model, surface roughness and waviness. In the investigated channel Reynolds number range (from 2000 to 12,000), the pin fins arrays with the largest height-to-pin diameter ratio show better thermal performances (Nu/Nu0 always greater than 2), however their heat sink efficiencies are above unity only for Re < 3000. In addition, the 45° oriented pin arrangement seems the most promising geometry due to high thermal efficiency, lighter weight and slightly lower manufacturing cost.

Numerical study of 3-D helical passive micromixer having both inlets at offset with blood as fluid

In the present study, two different micromixers have been evaluated for their mixing efficiencies with non-Newtonian working fluid blood. This helical micromixer has been chosen since it solves the problem of high mixing time during the mixing of fluids at the micro-level. This helical micromixer has both of its inlets at an offset to each other and is named TDHM-TO, i.e., 3D helical micromixer with inlet at offset. When this helical micromixer was compared with standard simple T-micromixer (STM), it is found that TDHM-TO requires much less mixing length than that of STM and still provides better mixing efficiency. Continuity equation, Navier-Stokes and species transport equations have been solved to investigate the mixing efficiency of the micromixers for non-Newtonian fluid blood. The study considers a wide range of mass flow rates (0.0004 kg/hr.–0.10 kg/hr.). It is being found that, for all values of mass flow rate, TDHM-TO performed much better than STM. E.g., for flow rate = 0.07 kg/hr., TDHM-TO provide a mixing efficiency of 74.41% compared to 4.93 of STM which is about 65.2% more than that of STM. STM showed a very poor result compared to TDHM-TO with only 7.64% of maximum mixing efficiency obtained with the flow rate = 0.1 kg/hr. compared to 72.84% of TDHM-TO. This TDHM-TO micromixer can be, thus, utilized in many chemicals, biochemical, and biomedical industries because of its higher efficiency and lower mixing length.

Experimental Performance Analysis of a Corrugation Type Solar Air Heater (CTSAH)

This paper explains the experimental performance evaluation of a Corrugated Type Solar Air Heater (CTSAH) for understanding its performance in a humid tropical climatic condition in Puducherry, India. This helps in understanding its effectiveness in using it for drying application of products like seafood, etc. Experiments were conducted at different mass flow rates and their effect on the heat gain, efficiency, friction factor heat transfer, etc., was analyzed. Experiments were carried out at different mass flow rates, i.e., M1 = 0.06 kg/s, M2 = 0.14 kg/s, M3 = 0.17 kg/s, M4 = 0.25 kg/s, M5 = 0.3 kg/s, and were conducted from 11:00 h to 14:00 h. The air inlet & air temperature is found to be at an average of 40°C whereas the incident solar radiation is at an average of 795 W/m². Experimental results show that the optimum performance of the CTSAH is in the mass flow rate range of 0.14–0.25 (kg/s). Also, the calculated useful heat produced, convective heat transfer coefficients, effective efficiency, optical efficiency provides knowledge on the potential use of the air heater.

Numerical analysis of hydrofluidisation food freezing with moving products in different aqueous solutions by using CFD and MPM approaches

Hydrofluidisation (HF) is an original method of food freezing that allows very high heat transfer coefficients to be reached and significantly reduces the freezing time of small foods. This paper presents a numerical study of HF for food products immersed in different liquids: binary solutions of ethanol (30%) and glycerol (40%) and a ternary solution of ethanol and glucose (15% and 25%). The particle movement (0.02 m diameter) was simulated using the Macroscopic Particle Model (MPM) approach to extend the CFD simulation by the particle flow, which affects the liquid phase velocity field. The numerical model developed in that study fully describes the hydrodynamics of HF process and is the most realistic out of all the numerical studies performed so far due to the ability to resolve the fluid flow locally on a smaller scale than in other models where the movement of foods in HF was introduced. Experiments with high-speed camera recordings validated the numerical model. A wide range of liquid mass flow rates in the range from 0.1 kg⋅s−1 to 2.0 kg⋅s−1 was investigated. As a result, heat transfer coefficients from 1 000 W⋅m−2⋅K−1 to 4 500 W⋅m−2⋅K−1 were reached, depending on the fluid mass flow rate. The liquid type had a minor effect on the heat transfer coefficient (HTC) but affected the behaviour of food samples. The effect of the food product suspension within the HF tank was noticed only for the ethanol solution with a moderate mass flow rate.

Pre-landing plans for Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) science operations

The Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) is a technology demonstration on the NASA Mars 2020 Perseverance rover. MOXIE is capable of producing 6–10 g/h of oxygen via solid oxide electrolysis of atmospheric carbon dioxide. The Mars 2020 mission has allocated MOXIE a minimum of ten oxygen-producing runs, each with approximately 1 h of oxygen production. Before landing, operations were planned to meet MOXIE's five success criteria. Run structure, constraints, and thorough definition and validation processes were defined. Before producing oxygen for the first time, several checkouts were planned to verify functionality of MOXIE's major subsystems. MOXIE's first oxygen-producing run was planned to produce up to 6 g/h of oxygen for approximately 1 h and measure a conservative range of current and voltage at two inlet mass flow rates. The remaining oxygen-producing runs were planned to measure performance using the largest permissible range of current, voltage and inlet mass flow rate for a wide range of atmospheric densities. Runs were designed to be flexible, allowing modification as operational knowledge accumulates throughout the mission. Validation of runs using models and hardware has demonstrated that MOXIE is ready for surface operations.

Assessment of the fluid-dynamic and acoustic behaviour of a swirl static mixer for after-treatment systems

An investigation on the acoustic transmission loss and the pressure drop caused by a mixer inducing element located downstream of a Diesel Exhaust Fluid (DEF) injection port was carried out in order to reduce the knowledge gap identified for this kind of after-treatment system elements. Transmission Loss measurements were performed at 4 mass flow rate conditions; 0, 100, 200 and 300 kg/h. Additionally, pressure drop measurements were registered for a range of mass flow rates, from 0 to 800 kg/h at steps of 50 kg/h, with similar flow and room temperatures. The post-processing and analysis included the application of a decomposition technique in the case of the transmission loss, which lead to understand the contribution of reflective and dissipative effects to the total attenuation. Reference results are provided for the particular geometry and kind of mixer element characterized, as well as the full extent of the results analysis and the insights of the decomposition analysis technique, and also different modelling possibilities have been explored. The conclusions indicate that, while usually overlooked, these devices may have a significant influence on the exhaust acoustics, mainly due to the influence of their presence on the attenuation of the after-treatment device as a whole.

Thermal entropy and exergy efficiency analyses of nanodiamond/water nanofluid flow in a plate heat exchanger

The study is aimed to understand the heat transfer coefficient and thermal entropy generation analyses of plate heat exchanger by using water-based nanodiamond nanofluids. The experiments were conducted in the volume concentration range: 0 ≤ ϕ ≤ 1.0%, the Reynolds number range: 140 ≤ Re ≤ 610, the mass flow rate range: 0.05≤ṁ≤0.183kg/s, and the Peclet number range from 895.78 ≤ Pe ≤ 3882.72, respectively. The effect of Reynolds number, Peclet number and particle volume loadings of nanodiamond nanofluids on heat transfer characteristics and entropy generation has been investigated. Water and nanodiamond nanofluids were considered as hot and cold medium in the plate heat exchanger, respectively, for the experimental study. The study reveals considerable augmentation in heat transfer coefficient and Nusselt number with an increase of nanofluid particle loadings. The study showed 32.50%, 55.47%, 35.11%, 22.80%, and 18.93% enhancements in overall heat transfer coefficient, heat transfer coefficient, Nusselt number, pressure drop and pumping power compared to base fluid at a Reynolds number of 526.37 at ϕ = 1.0%. Improved effectiveness, number of transfer units and exergy efficiency of 14.41%, 32.81% and 19.72% was observed at ϕ = 1.0% and at a Reynolds number of 526.37 against base fluid data. The thermal entropy and friction entropy generation was showed decreasing and increasing trends respectively, in the measured particle volume loadings. The Bejan number and entropy generation number demonstrated the roles of heat transfer and friction factor in the entropy generation. From the experimental results a new Nusselt number and friction factor correlations were proposed.

Numerical analysis of the flow rig for UWS spray examination in exhaust system-relevant conditions

In the present study, a flow rig with optical access intended for spray investigations in exhaust system-relevant conditions was analysed in terms of flow and temperature in the spray area using numerical simulations. The operation of the rig was examined for a wide range of exhaust mass flow rates, temperatures and various forms of UWS (urea-water solution) spray plumes. The locations of the injector and thermocouple were verified. Both conventional and flash-boiling injections were considered to assess the effect of the interaction of sprays with a gas flow. The results showed a highly uniform flow in the visualisation area, with only minor fluctuations near the walls. A similar observation was carried out for the temperature distribution. It was found that the extreme operating conditions caused substantial deformations of the spray plumes. However, the selected injector location allowed us to properly observe the spray formation regardless of the flow conditions. The study showed that the examined test rig enabled reliable spray investigations for a wide range of operating points.

Falling film evaporation and pool boiling heat transfer of R1233zd(E) on thermal spray coated tube

• Falling film evaporation heat transfer of R1233zd(E) was experimentally investigated. • Up to 4.2-fold heat transfer enhancement could be obtained by thermal spray coating. • R1233zd(E) achieved a lower heat transfer coefficient than R134a at 20 °C. Falling film evaporators have been expected as an alternative to flooded evaporators for reducing the refrigerant usage. It is important for the enhancement of the film evaporation heat transfer to keep a liquid film and promote nucleate boiling in the liquid film. This study focused on nucleate boiling heat transfer in the liquid film by thermal spray coating that can be applied regardless of the material of heat transfer tubes. The heat transfer performance of falling film evaporation on a horizontal copper tube was experimentally evaluated. Since nucleate boiling phenomena, such as activation of nucleation sites and bubble behaviors in the liquid film, strongly depend on the physical properties of the refrigerant, the experimental results for R1233zd(E), one of the alternative refrigerants with low GWP, were compared with those for R134a. Two types of tubes were used: the smooth tube and the thermal spray coated tube fabricated by an arc wire spraying method, with the outer diameter of 19.05 mm and the heating length of 50 mm. Pool boiling experiments were also conducted to confirm the wall superheat for nucleate boiling. The heat transfer coefficients were evaluated with a film mass flow rate range of 8.5 × 10 −3 to 6.3 × 10 −2 kg/(m·s), a heat flux range of 10 to 85 kW/m 2 , and a saturation temperature at 20 °C. The effects of the structure of the heating surface, heat flux, and thermophysical properties of the refrigerant on the heat transfer performance are discussed. Results show that the heat transfer of the falling film became the nucleate boiling dominant with a sufficient heat flux and liquid film flow rate. The thermal spray coated surface enhanced not only the nucleate boiling but also the liquid spreading by the vapor bubbles in the liquid film, and thus the coated tube produced higher heat transfer coefficients of 2.1 to 4.8 times those for the smooth tube. The wall superheat at the onset of nucleate boiling was higher for R1233zd(E) than for R134a, because R1233zd(E) has a higher surface tension and lower vapor density. Thus, the pool boiling and falling film evaporation heat transfer coefficients were lower for R1233zd(E) than for R134a.

Forced Convection Heat Transfer Outside Enhanced Tubes with Different Surface Structures

To promote the development of enhanced tubes in heat exchangers, forced convection experiments were carried out using R410A in the annular region outside enhanced tubes. Three enhanced tubes were investigated by experiments to evaluate the heat transfer performance; with different surface structures of novel fin arrays (C-enhanced tube), newly-developed combined dimples (L-enhanced tube) and sandblasted surface (P-enhanced tube); with the 19.05 mm outer diameter; with mass flow rate range of 40-110 kg/m2s. For single-phase and condensation experiments at various saturation temperatures, the C-enhanced tube showed the best heat transfer performance and produced heat transfer coefficients of 4.25 and 3.8 times that of the smooth tube. The results of changing outlet vapor quality (0.3-0.8) of flow boiling experiments indicated that the L-enhanced tube showed the best evaporation characteristics and yielded heat transfer coefficients 2.1-3.9 times that of the smooth tube. Surprisingly, instead of showing the heat transfer performance advantage of the P-enhanced tube, heat transfer deterioration occurred despite numerous micro dimples on the surface. In addition, the pressure drop characteristics were also discussed, and the experimental results were evaluated by empirical correlations.

In situ measurement and closed-loop control for powder supply processes

The powder mass flow rate is one of the main parameters regarding the geometrical precision of built components in the additive manufacturing process of laser metal deposition. However, its accuracy, constancy, and repeatability over the course of the running process is not given. Reasons among others are the performance of the powder conveyors, the complex nature of the powder behavior, and the resulting issues with existing closed-loop control approaches. Additionally, a direct in situ measurement of the powder mass flow rate is only possible with intrusive methods. This publication introduces a novel approach to measure the current powder mass flow rate at a frequency of 125 Hz. The volumetric powder flow evaluation given by a simple optical sensor concept was transferred to a mass flow rate through mathematical dependencies. They were found experimentally for a nickel-based powder (Inconel 625) and are valid for a wide range of mass flow rates. With this, the dynamic behavior of a vibration powder feeder was investigated and a memory effect dependent on previous powder feeder speeds was discovered. Next, a closed-loop control with the received sensor signal was implemented. The concept as a whole gives a repeatable and accurate powder mass flow rate while being universally retrofittable and applicable. In a final step, the improved dynamic and steady performance of the powder mass flow rate with closed-loop control was validated. It showed a reduction of mean relative errors for step responses of up to 81% compared to the uncontrolled cases.

A Study on flow boiling characteristics in a minichannel and conventional channel

The flow boiling characteristics of minichannel and conventional have been evaluated for the various mass flux and heat flux. The impact of channels heat transfer analysis was carried out by mixture model (MM) of ANSYS Fluent by using water as a working fluid. The aim of this paper to find the better heat transfer in the channels at a different range of mass flow rates (0.020kg/s to 0.040 kg/s) and heat fluxes (1000 W/m2 to 2000W/m2). The analysis was explained with help of output parameters like vapour fraction, heat transfer coefficient, evaporative thin film thickness, temperature difference in channel wall side and film water temperature side, Nusselt number and friction factor. The validation was done with the help of the previous paper. It was observed that friction factor is calculated for various mass flow rate in channels, is lower from smaller diameter pipe but heat transfer is more for the case of bigger diameter. The minimum mass flow rate increases the wall surface temperature as well as high heat flux increase the channel wall temperature. The 4 mm conventional channel is better heat transfer rate compared to 3 mm minichannel.

CCS at Depleted Gas Fields in North Sea: Network Analysis

As part of development of the Dutch North Sea for CO2 storage, this study presents an investigation into offshore transport and storage network design. With depleted gas fields providing storage capacity, the low post-production reservoir pressures pose challenges to defining safe injection procedures. Pressure and temperature profiles are computed for a range of mass flow rates for well – reservoir combinations that are typical for gas fields in the Dutch part of the North Sea. These profiles illustrate the trade-offs that exist between injection of CO2 in gas phase versus injection of liquid CO2. In the latter case the injection rates that can be achieved are significantly higher, but limitations to the temperature in the well often lead to a significant minimum flow rate that limits flexibility of operations. The limitations arise from wellhead integrity and from hydrate formation at bottomhole or close to the well in the reservoir. Three potential networks of depleted fields are used to compare overall feasible injection rates over timeline of 30 years. While all networks can store the assumed target rates, the different well and reservoir properties result in substantial differences in well and reservoir count and, by consequence, in effort required to re-develop fields and wells for CO2 storage. The networks have different levels of operational flexibility, arising from flow constraints, and of network complexity, related to field and well count. The results from this study show that a network of depleted gas fields can be used to reach the injection rates commonly associated with large-scale CO2 capture and that the challenges related to low reservoir pressure can be managed.

Investigation and optimization on cooling performance of a novel double helix structure for cylindrical lithium-ion batteries

Abstract Liquid cooling system was critical to keep the performance of lithium-ion battery due to its good conductivity to keep battery working in a cool environment. In this study, a novel double helix cooling structure was designed for an 18650 lithium battery. The numerical simulation was carried out to investigate the effects of the coolant mass flow rate (M), helix groove pitch (P) and flow diameter (D) on cooling performance. The design points obtained by Latin hypercube sampling were calculated numerically. Kriging approximate model method was adopted to reduce computing time. Using Non-dominated Sorting Genetic Algorithm II obtained the Pareto solution, and the multiple criteria decision making (MCDM) algorithm was used to sort the optimal solution set. The results showed that increasing mass flow rate can effectively lower the maximum temperature and temperature difference of the battery within a certain range of mass flow rate. When the mass flow rate increased to a certain value, the benefit from increasing the mass flow was limited. And the pitch and diameter would also have a tendency to the decrease of the maximum temperature or even the opposite result when they exceeded a certain value. The best cooling performance can be obtained when the mass flow rate is 1.94 × 10−3 kg/s, the pitch is 100 mm and the diameter is 0.4 mm. The novel cooling structure proposed in this study can provided a new approach for the structure design of the liquid-cooled cylindrical battery thermal management system.

Influences of slotted blade on performance and flow structure of a transonic axial compressor

Main reason of compressor instability is boundary layer separation on the surface of blades. As one of flow control methods of the compressor, slotted blade has attracted many researchers’ attention because of its simple geometric structure and remarkable flow control effect. In order to evaluate its availability in the compressor, a type of convergent slot is designed to implement in a single-stage transonic axial compressor. Three configurations, i.e. rotor slot, stator slot and rotor-stator combined slot, are introduced to study the aerodynamic performance of compressor by numerical simulations. Furthermore, flow structures have been analyzed to explain the corresponding mechanism. The results show that overall stability margin of the compressor has been improved by flow control with slotted blade. Behavior of the rotor slot is better than that of the stator slot, but due to mass flow leakage in the slot, peak efficiency and chocking mass flow rate of the compressor are decreased by 1.18% and 3.8% respectively. The low momentum flow on pressure surface is sucked into the jet slot of stator blade, which improves the overall stability margin of 0.63%. The combined scheme with slotted rotor and slotted stator has obtained the best aerodynamic behavior with the increase of the overall stability margin of 2.83%. During the future research, main goal will be improvement of the compressor performance and extension of the mass flow rate range.

FEA design and analysis of flow sensor

In this research article a resonating tube was designed for Coriolis mass flow Sensor (CMFS) and sensor locations was varied. Resonant tube was designed to withstand maximum pressure with governing equations of coupled fluid structure problems. What is the result of sensor location on phase shift is the main goal of this research study. For omega type resonant tube from the base of vertical omega tube, the sensor locations have been varied from 60 mm to 120 mm in the present research article. CMFS is based on Coriolis Effect principle. For modelling of tube design, pro-E was used, and for analysis purpose Ansys 14.5 was used. Sensor locations and phase shift simulation results have been validated with experimental results. With the help of experimental results validation of sensor locations and phase shift simulations has been done. Omega type test configuration having L = 300 and D = 400 mm was used for experimentation for tube materials. The maximum values of phase shift was observed around 120 mm sensor location for 0.1 and 0.2 kg/s mass flow rate. It was observed from result that phase shift values are linearly varying with all range of mass flow rates. The resonant frequency is 24 Hz obtained from modal analysis for copper omega resonating tube.
