Water Flow In Channel Research Articles

Simulação numérica bidimensional do escoamento em canal com obstáculos submersos usando o método do reticulado de Boltzmann

A two-dimensional numerical simulation of the water flow in a rectangular channel with submerged obstacles distributed alternately along its banks is presented. The governing equations of flow are the shallow water equations, which will be solved by the Boltzmann lattice method (LBM) with multiple relaxation times (MRT). The non-slip bounce-back scheme was used on walls and obstacles, constant discharge at the inlet and fixed depth at the outlet of the channel. Due to the characteristics of the problem to be simulated, a large eddy simulation (LES) technique was incorporated into the computational code, which allows to obtain results that are closer to the actual behavior of the flow. In addition, the stability of the simulation at all points of the mesh is evaluated for each step of time and, together with the property of the consistency of the LBM, the convergence of the solution is obtained. The simulation provides the depth, velocities in the x and y directions, and the magnitude of water vorticity.

Modelling and analysis of the JET EP2 neutral beam full energy ion dump curved end plate

This paper describes enhanced modelling of the power loading on the current JET full energy ion dump (FEID) curved end plate, and the new end plate design with improvements to the power handling capabilities and additional features to improve fatigue life. Monte-Carlo simulations of each of the nine residual ion components which are intercepted by the plate shows a peak power density of 20MW/m2 and compares well with recently installed fast thermocouple measurements. Analytical calculations and simulations with the Charged Particle Optics (CPO) code are used to investigate the potential for movement of the residual ion focus due to space charge effects. Cooling performance is significantly enhanced by improved water channel flow which is both modelled and confirmed by experiment. Fatigue life, calculated from ANSYS modelling is improved using a slot arrangement to relieve stresses created from focussed heat load distribution.

Controlling Strategies for Efficent Device Operation and Degradation Alleviation in Concentrated Integrated Photo-Electrochemical Devices

The direct conversion of solar energy and water into a storable fuel via integrated photo-electrochemical (IPEC) devices is numerically investigated. Here, we focus on a device architecture which uses concentrated solar irradiation to reduce the use of rare and expensive components such as light absorbers and catalysts. For such devices, it is of particular importance that the device operates with stable efficiency and production rates. The degradation of the materials over the lifetime of the device as well as the daily and seasonal changes in incoming irradiation pose a challenge for the stable and secure supply of fuel from such devices. To tackle these issues, we develop performance optimization strategies utilizing device design, component and material choice, and adaptation of operational conditions. We used a 2D coupled multi-physics model using finite element and finite volume methods to predict the performance of the concentrated IPEC device [1]. This device model was used to predict the performance of the device exposed to changes in operating conditions (short term transients in irradiation, longer term transients due to degradation) and, subsequently, to predict how controlling of the operating conditions (mass flow rate of reactant, irradiation flux and active areas) can be used to counteract performance decrease. Maximum power points, V op and I op which are calculated from the output of the CIPEC device, serve as the inputs for the proportional–integral–derivative (PID) controller. The mapped data of operating points for varied range of input irradiation and water mass flow rates (or flow velocities) is calculated using our detailed 2D multi-physics model. This data is used in the PID controller’s algorithm. The PID controller is connected to the water (reactant) mass flow rate controller, irradiation shade, and flow channel ports in order to control input water flow rate, irradiated area and electrochemically active area of the IPEC device and, correspondingly, to control the performance of the device. The steady state results predict that the current-voltage curves of the electrochemical component (EC), with varying mass flow rates, intersect in a small potential region (figure 1.a), giving rise to two distinctive regions of operation [2]. Region I, corresponding to a low operating current density zone, is affected by temperature effects, leading to increasing slopes of the current-voltage curves of the EC for smaller temperatures. Region II, corresponding to a large operating current density zone, is characterized by mass transport limitations which lead to increased saturation currents of the EC with increasing mass flow rates. The formation of these two characteristic operational regions leads to specific trends and tradeoffs in the objective functions of solar-to-hydrogen (STH) efficiency and H2 production rates when increasing the irradiation concentration and consequently require opposite controlling actions. These characteristic operating zones provide the basis for the formulation of controlling strategies. These strategies enhance the performance of the device and help in alleviating effects on the performance due to device degradation. Utilizing a simple PID controller, IPEC devices can be operated without significant decrease in performance for timescales relevant for degradation. This is even possible at very high irradiation concentrations, provided the input water flow velocity is at least 0.2 m/s. The effect of degradation is particularly pronounced if the operation is close to the maximum power point of the PV. The device degradation and the corresponding decrease in performance over the lifetime of the system can be controlled. For operation of an example device made of Si-based PV and rare catalysts at C = 707, a 12% degradation in STH efficiency can be compensated with a seven-fold increase in the water mass flow rate (figure 1.b). However, only if the operating point remains in region II, i.e. the degradation overpotential in the EC is limited to about 250 mV. Our simulation frameworks in combination with a simple controller model provides evidence that a concentrated IPEC device can always be operated at optimized performance even though there are short and long term transients affecting the operation of the system. Consequently, controlling strategies show to be a simple approach to alleviate the effects of device degradation over the lifetime and short-term transients occurring due to e.g. irradiance fluctuations.

Local Condensation Heat Transfer Characteristics of Refrigerant R1234ze(E) Flow Inside a Plate Heat Exchanger

In the present study, local condensation heat transfer coefficients of the R1234ze(E) inside a vertical plate heat exchanger (PHE) were investigated experimentally. In the experiment, three vertical flow channels are formed in the test section where refrigerant flows downward in the middle channel and cooling water flows upward in other two channels. The test section consists of eight plates: two of them form a channel of chevron type PHE for refrigerant flow channel, other two flat plates are set for heat transfer measurements, and another consist on cooling water flow channel. Down flow of the condensing refrigerant R1234ze(E) in the center channel releases heat to other channels of cooling water. In order to measure local heat transfer characteristics, a total of 60 thermocouples were set at middle of flow direction and also in the right and left sides of plates in test section. Experiments were conducted for mass fluxes ranging from 10[Formula: see text]kg/m2s to 50[Formula: see text]kg/m2s. The measurement results show that local heat transfer coefficients decrease with increase of wetness with different values in horizontal direction. Further, characteristics of local heat flux and wall temperature distribution as a function of distance from inlet to outlet of refrigerant channel were explored in detail.

Vortex heat transfer enhancement in the narrow plane-parallel channel with the oval-trench dimple of fixed depth and spot area

The article is devoted to the analysis of vortex heat transfer enhancement due to the use of oval-trench dimples. The main role in the understanding of this process is associated with the application of the technologies developed in engineering practice thanks to design decisions. As a result, prevailing interest has been paid to a spherical dimple when a spot diameter is chosen as a characteristic size, whereas hydraulic losses depend on the dimple-to-device size ratio. Progress in vortex heat transfer enhancement due to the use of oval dimples is connected with the explanation of the mechanism of generation of both vortex structures in dimples and spiral vortices behind them. An abrupt increase of heat transfer in the vicinity of the spherical dimple due to the restructuring of the flow structure in the dimple with two vortices to that in the dimple with one spiral vortex made it possible to propose a new shape of a surface vortex generator – an oval dimple located at an angle of inclination to the incoming flow and consisting of two spherical dimple halves separated by a cylindrical insert. The generation of vortex structure in this case is rather stable and intense in comparison to spherical dimple. The numerical results for vortex heat transfer enhancement in the turbulent water flow in the rectangular narrow channel with spherical, 10°-truncated conical and oval dimples of the same spot area and depth at the heated wall are presented. In the article, central attention is given to the mechanism of secondary flow restructuring and heat transfer enhancement due to increase in a relative length and width of an oval dimple followed by the formation of a long spiral vortex in it. The change in the length of the oval dimple (in terms of its width) from 1 to 6.78 allowed one to rationally mount spiral vortex surface generators in the narrow channel with high thermal and thermal-hydraulic efficiencies, significantly exceeding the identical characteristics of channels with spherical and conical dimples. In this case, moderate hydraulic losses in the channel with an oval-trench dimple, when its length is increased to 6.78, are comparable to those in the channel with a basic spherical dimple.

Analysis and generalization of experimental data on heat transfer to supercritical pressure water flow in annular channels and rod bundles

Experimental data on heat transfer to supercritical pressure water presented at ISSCWR-5, 6, and 7 international symposiums—which took place in 2011–2015 in Canada, China, and Finland—and data printed in recent periodical scientific publications were analyzed. Results of experiments with annular channels and three- and four-rod bundles of heating elements positioned in square or triangular grids were examined. Methodology used for round pipes was applied at generalization of experimental data and establishing of correlations suitable for engineering analysis of heat exchange coefficient in conditions of strongly changing water properties in the near-critical pressure region. Empiric formulas describing normal heat transfer to supercritical pressure water mowing in annular channels and rod bundles were obtained. As compared to existing recommendations, suggested correlations are distinguished by specified dependency of heat exchange coefficient on density of heat flux and mass flow velocity of water near pseudo-critical temperature. Differences between computed values of heat exchange coefficient and experimental data usually do not exceed ±25%. Detailed statistical analysis of deviations between computed and experimental results at different states of supercritical pressure water flow was carried out. Peculiarities of deteriorated heat exchange were considered and their existence boundaries were defined. Experimental results obtained for these regimes were generalized using criteria by J.D. Jackson that take the influence of thermal acceleration and Archimedes forces on heat exchange processes into account. Satisfactory agreement between experimental data on heat exchange at flowing of water in annular channels and rod bundles and data for round pipes was shown.

Thermal and electrical performance of a hybrid design of a solar-thermoelectric system

An evacuated tube heat pipe solar collector was fitted with four thermoelectric modules and four water cooling jackets on the condenser side to produce electricity and hot water simultaneously. Each cooling jacket had six mini water-flow channels inside it. Solar heat was absorbed and collected by the evaporator section. Experiments were conducted under outdoor environment with various water coolant flow rates. Once-through coolant water flow was adopted as a first step. Further investigations would be conducted to incorporate an insulated hot water storage tank to evaluate the system economic viability as a power producer and hot water generator. Temperatures were recorded along the evaporator and condenser sections of the heat pipe, thermoelectric junction temperatures and inlet/outlet water channels. This paper presents the experimental results obtained. Typical daily experimental results showed that electrical output voltage and hot water temperatures peaked around 15.30 before decreasing towards the evening. Total electrical efficiency was very low, about 0.16% at around 15.30h.

Active subglacial lakes and channelized water flow beneath the Kamb Ice Stream

Abstract. We identify two previously unknown subglacial lakes beneath the stagnated trunk of the Kamb Ice Stream (KIS). Rapid fill-drain hydrologic events over several months are inferred from surface height changes measured by CryoSat-2 altimetry and indicate that the lakes are probably connected by a subglacial drainage network, whose structure is inferred from the regional hydraulic potential and probably links the lakes. The sequential fill-drain behavior of the subglacial lakes and concurrent rapid thinning in a channel-like topographic feature near the grounding line implies that the subglacial water repeatedly flows from the region above the trunk to the KIS grounding line and out beneath the Ross Ice Shelf. Ice shelf elevation near the hypothesized outlet is observed to decrease slowly during the study period. Our finding supports a previously published conceptual model of the KIS shutdown stemming from a transition from distributed flow to well-drained channelized flow of subglacial water. However, a water-piracy hypothesis in which the KIS subglacial water system is being starved by drainage in adjacent ice streams is also supported by the fact that the degree of KIS trunk subglacial lake activity is relatively weaker than those of the upstream lakes.

Experimental investigation of a flexible high‐water protection system in a down‐scale water channel flow

AbstractAs part of an interdisciplinary major project regarding the development of a flexible and efficiently installable high‐water protective system we investigated the behaviour of different system parts of flexible channel walls (thin, plastic slides/membranes) and types of self‐installing water barricades subjected to different water channel flows experimentally and numerically. In the experiments we studied the strain of different flexible channel walls and the efficiency of various water barricades in a down‐scale model by optical deformation, flow velocity and time measurements, respectively. We varied the water height as well as the representative flow velocity of the water channel flow and we also examined the influence of water waves onto these high‐water protective system parts. Selected results will be shown and described concerning the stress on the used model‐slide. In addition we applied similarity theory not only for general data presentation but also to generate findings regarding a future practical implementation in technical applications.

Relation Between Current Density Distribution in Land-Channel Direction and Presence of Liquid Water in Proton Exchange Membrane Fuel Cell Flow Channel

Since most of the PEMFCs have land-channel geometry in their flow field, the distance between the flow channel to the catalyst layer is not uniform. The distance is longer from the flow channel to the catalyst layer under the land area than to the catalyst layer under the channel area. This difference causes the non-uniform current density in land-channel direction, and the distribution largely depends on the operating conditions. As the inlet gas humidity in the operating condition decreases, the trend in the current density distribution changes from high local current under the channel to relatively uniform, and to higher local current under the land (Figure 1). This trend is due to the combined effects of (1) non-uniform oxygen transport resistance, (2) non-uniform liquid water transport distance causing the local flooding under the land area at wet condition, and (3) the tendency of faster membrane dryout under the channel area at dry condition. In order to investigate the distributions of various parameters in the land-channel direction, a small-scale segmented cell with about 300-micron resolution was developed by the authors’ group, and successfully measured the current and high-frequency resistance distribution in the land-channel direction. Distribution of oxygen transport resistance from the flow channel to the catalyst layer was also measured using limiting current technique. In this study a new segmented cell is developed. Using the transparent cathode plate the behavior of liquid water in cathode flow channel can be observed, and simultaneously the current density distribution is measured in land-channel direction. With this cell the relation between the current density distribution in the land-channel direction and the presence of liquid water is investigated. First, it is studied that at what gas humidity and at what overall current density the liquid water starts emerging from the gas diffusion layer surface to the flow channel. This provides us the information about the dependency of the liquid water emergence location on the current density distribution is studied. Then, how the presence of liquid water in the flow channel changes the current distribution is studied. Figure 1

Mid- to late-Holocene environmental evolution of the Loire estuary as observed from sedimentary characteristics and benthic foraminiferal assemblages

We used sedimentological and foraminiferal characteristics of four sedimentary cores, supported by paleogeographical and historical data, to reconstruct the depositional history of the inner Loire estuary (Near Saint-Nazaire, France) and the response of benthic foraminifera to the mid- to late-Holocene marine flooding of the incised valley. These were further used to evaluate the consequent changes in estuarine morphological and hydro-sedimentary patterns during this time period. Our results described significant changes in hydro-sedimentary dynamics over the past ~6kyrsBP. At our location, these changes expressed the combined influence of marine (e.g., tide, storm waves) and fluvial dynamics (e.g., floods), which are linked, on a broader scale, to sea-level variations and the regional climate regime. Three main periods stand out: (1) from ~6.0 to ~2.5kyrsBP, when the sea-level rise slowed down, a large brackish bay extended over and around the study area. The fine-grained tidal rythmites recorded north of the Bilho bank (the main tidal bar located in our study area) indicated a calm depositional environment, protected from the main riverine influence. The presence of thick flood deposits from ~5.4 to ~4.0kyrsBP near the Bilho bank indicates further the dominance of humid conditions. (2) From ~2.5 kyrs BP to ~1850CE (pre-industrial state), sea-level stabilized at its present value, and the pre-existing bay was progressively infilled. North of the Bilho bank, near a major mudflat (Méan), the generally homogenous sedimentation composed of silty muds rich in organic matter indicated a sheltered environment; the main water flow channel being located south of the Bilho bank. Within this overall homogenous sedimentation, foraminiferal assemblages described rather accurately the progressive infilling of the valley (indicated by a decrease in the proportions of outer estuarine species), accompanied with the channelization of the main entering marine currents (tide, storm waves) (indicated by an increase in the proportions of transported species from the adjacent upper continental shelf), and finally the buildup of the Méan mudflat and the stabilization of the environment to its present day configuration (indicated by the dominance of autochthonous inner estuarine species). (3) Since 1850CE, the human impact progressively modified the general landscape of our study area with the construction of the Saint-Nazaire shipyard, the digging of the northern navigation channel and the polderization of the northern Bay. The southern channel was progressively abandoned by the main water flow in favor of the newly dug northern channel, causing the southern migration of the Bilho sandbank and the progressive filling of the southern channel.

Measurement of Taylor bubble shape in square channel by microfocus X-ray computed tomography for investigation of mass transfer

This paper addresses the measurement of the dynamic evolution of Taylor bubble volume and interfacial area during mass transfer. Carbon dioxide (CO2) Taylor bubbles were placed in countercurrent water flow in a square channel. Microfocus X-ray radioscopy enabled the measurement of volumetric dissolution rates. The measurements were calibrated by microfocus X-ray computed tomography scans of non-dissolving air Taylor bubbles. The reconstruction algorithm was adapted to correct the slight position shift of the Taylor bubble during the tomographic scan. The obtained three-dimensional representation of the Taylor bubble's shape enabled the measurement of Taylor bubble's true volume and interfacial area, which were correlated to the two-dimensional radioscopic measurements. The volumetric dissolution rates were measured in a square milli-channel with hydraulic diameter of dh=6mm. Furthermore, the thin film region of the constricted Taylor bubble's surface near the planar channel walls was extracted from the data and the ratio to the total Taylor bubble surface was computed.

The HEC RAS model of regulated stream for purposes of flood risk reduction

Abstract The work highlights the modeling of water flow in open channels using 1D mathematical model HEC-RAS in the area of interest Lopuchov village in eastern Slovakia. We created a digital model from a geodetic survey, which was used to show the area of inundation in ArcGIS software. We point out the modeling methodology with emphasis to collection of the data and their relevance for determination of boundary conditions in 3D model of the study area in GIS platform. The BIM objects can be exported to the defined model of the area. The obtained results were used for simulation of flooding. The results give to us clearly and distinctly defined areas of inundation, which we used in the processing of Cost benefit analysis. We used the developed model for stating the potential damages in flood vulnerable areas.

Characterizing dynamic hysteresis and fractal statistics of chaotic two-phase flow and application to fuel cells

In this study, we analyze the stability of two-phase flow regimes and their transitions using chaotic and fractal statistics, and we report new measurements of dynamic two-phase pressure drop hysteresis that is related to flow regime stability and channel water content. Two-phase flow dynamics are relevant to a variety of real-world systems, and quantifying transient two-phase flow phenomena is important for efficient design. We recorded two-phase (air and water) pressure drops and flow images in a microchannel under both steady and transient conditions. Using Lyapunov exponents and Hurst exponents to characterize the steady-state pressure fluctuations, we develop a new, measurable regime identification criteria based on the dynamic stability of the two-phase pressure signal. We also applied a new experimental technique by continuously cycling the air flow rate to study dynamic hysteresis in two-phase pressure drops, which is separate from steady-state hysteresis and can be used to understand two-phase flow development time scales. Using recorded images of the two-phase flow, we show that the capacitive dynamic hysteresis is related to channel water content and flow regime stability. The mixed-wettability microchannel and in-channel water introduction used in this study simulate a polymer electrolyte fuel cell cathode air flow channel.

Plugging properties and profile control effects of crosslinked polyacrylamide microspheres

ABSTRACTIn this article, the morphology, particle size, and plugging properties of crosslinked polyacrylamide (CPAM) microspheres were investigated through optical microscopy, scanning electron microscopy (SEM), nuclear‐pore membrane filtration experiments, a micro‐visual model, sandpack experiments, parallel twin‐tube plugging, and oil displacement experiments. The results revealed that the primary particle sizes of the CPAM microspheres ranged from several hundreds of nanometers to 5 μm; however, after the microspheres were fully swelled in water, their sizes increased by approximately five times of their original sizes. As a CPAM microsphere dispersion system had good dispersibility and deformation capabilities, a 1.2 μm nuclear‐pore membrane as well as the deep part of a sandpack tube could be effectively plugged. Consequently, the flow diversion effect was achieved in the vertical and planar directions. When the CPAM microspheres migrated in porous media, they could displace residual oil on the pole wall and water flow channel to realize the synchronization of profile control and coordination and improve recovery efficiency. © 2016 Wiley Periodicals, Inc.

Simulation of 2D Saint-Venant equations in open channel by using MATLAB

2D surface flow models are useful to understand and predict the flow through breach, over a dyke or over the floodplains. This paper is aimed at the surface flows to study the behavior of flood waves. The open channel water flow in drains and rivers is considered in view of the fact that such flows are the source of flash flood. In order to predict and simulate the flood behavior, a mathematical model with the initial and boundary conditions is established using 2D Saint-Venant partial differential equations. Next, the corresponding model is discretized by using the explicit finite difference method and implemented on MATLAB. For the testing and implementation purpose a simple rectangular flow channel is considered. The output parameters like height or depth of water z (m), the fluid velocity u (m/s) and the volumetric flow rate Q (m3/sec) are simulated numerically and visualized for the different time steps. The initial simulation results are useful to understand and predict the flood behavior at different locations of flow channel at specific time steps and can be helpful in early flood warning systems. It is also suggested that the coupling of the subsurface flow with the surface flow may provide even better approximations for the flood circulation.

Pore-scale supercritical CO2 dissolution and mass transfer under imbibition conditions

In modeling of geological carbon storage, dissolution of supercritical CO2 (scCO2) is often assumed to be instantaneous with equilibrium phase partitioning. In contrast, recent core-scale imbibition experiments have shown a prolonged depletion of residual scCO2 by dissolution, implying a non-equilibrium mechanism. In this study, eight pore-scale scCO2 dissolution experiments in a 2D heterogeneous, sandstone-analog micromodel were conducted at supercritical conditions (9MPa and 40°C). The micromodel was first saturated with deionized (DI) water and drained by injecting scCO2 to establish a stable scCO2 saturation. DI water was then injected at constant flow rates after scCO2 drainage was completed. High resolution time-lapse images of scCO2 and water distributions were obtained during imbibition and dissolution, aided by a scCO2-soluble fluorescent dye introduced with scCO2 during drainage. These images were used to estimate scCO2 saturations and scCO2 depletion rates. Experimental results show that (1) a time-independent, varying number of water-flow channels are created during imbibition and later dominant dissolution by the random nature of water flow at the micromodel inlet, and (2) a time-dependent number of water-flow channels are created by coupled imbibition and dissolution following completion of dominant imbibition. The number of water-flow paths, constant or transient in nature, greatly affects the overall depletion rate of scCO2 by dissolution. The average mass fraction of dissolved CO2 (dsCO2) in water effluent varies from 0.38% to 2.72% of CO2 solubility, indicating non-equilibrium scCO2 dissolution in the millimeter-scale pore network. In general, the transient depletion rate decreases as trapped, discontinuous scCO2 bubbles and clusters within water-flow paths dissolve, then remains low with dissolution of large bypassed scCO2 clusters at their interfaces with longitudinal water flow, and finally increases with coupled transverse water flow and enhanced dissolution of large scCO2 clusters. The three stages of scCO2 depletion, common to experiments with time-independent water-flow paths, are revealed by zoom-in image analysis of individual scCO2 bubbles and clusters. The measured relative permeability of water, affected by scCO2 dissolution and bi-modal permeability, shows a non-monotonic dependence on saturation. The results for experiments with different injection rates imply that the non-equilibrium nature of scCO2 dissolution becomes less important when water flow is relatively low and the time scale for dissolution is large, and more pronounced when heterogeneity is strong.

Feedback of the Glottal Jet Flow with Supraglottal Wall Oscillations

Within this study the influence of wall oscillations in the supraglottal space on the evolution of the glottal jet is investigated. Special focus is laid on the modification of the jet evolution in space and time when small varicose vibrations are excited externally on the walls of the second constriction (ventricular folds) in the supraglottal space. The experiments are carried out in a water flow channel representing a 3:1 upscaled model of the glottal region. Instead of fixed walls in the second constriction we use silicone membranes with an internal air cushion. Sinusoidal pressure oscillations of various frequencies are excited from outside pressure lines. Flow studies show that the glottal deflection in the supraglottal space is highly sensitive to these weak oscillations, hinting on the non-linear interaction of the oscillatory waves with the shear-layer roll-up of the jet. This is known as modelocking in jet dynamics and is expected to have consequences on the sound spectrum in phonation, too.

Optimization of a dual capture element magnetic separator for the purification of high velocity water flow

In this paper a magnetic separator based on the use of a cascade arrangement of two identical capture elements has been optimized and verified. Such a separator is intended for the separation of fine particles of iron from flowing water at high velocity. The optimization has concerned the search for the excitation current and the distance between the capture elements that permit the extraction of the particles from a water flow in a circular channel at an average velocity u fav = 1.05 m/s. For such optimization we have minimized the objective function that is the distance between the capture position of a particle initially situated at a specific position and the central point of the last capture element of the arrangement. To perform the minimization, we have applied the Tabu search method. To validate the obtained results experimental verification based on the control of the evolution of the captured particle buildup and the quantifying of the separated volume of particles was achieved.
