Flow cross-sectional area (m2).
Flow cross-sectional area, m 2. Impedance parameter.
Various approaches to optimize the positions of the ICVs and the valve's flow cross-sectional area have been published recently.
With consideration of temperature influence on water viscosity and the effective flow cross-sectional area of porous channels, the model can satisfactorily reflect the temperature effects.
Here, RΩ1 is defined as the ratio of flow cross-sectional area to the fluid washcoat perimeter and RΩ2 is defined as the ratio of washcoat cross-sectional area to the fluid washcoat perimeter.
Three issues critical to optimizing channel design and mitigating channel flooding in PEM fuel cells are fully discussed: liquid water buildup towards the fuel cell outlet, saturation spike in the vicinity of flow cross-sectional heterogeneity, and two-phase pressure drop.
These representative margin points were transferred to the corresponding flow cross-sectional image (Fig. 2(F)) and en face projection maps (Figs. 2(C), 2(D)).
Results of present experimental research indicate that different correlations selected in the study can be used with reasonable accuracy for designing the coiled finned-tube heat exchangers, if they are applied with suitable method of calculation of free-flow cross-sectional area.
While when the flow system is described to be in steady flow, there will be no change in the mass flow rate through all cross sectional areas of the flow passage, hence the mass flow rate is assumed as a constant, irrespective of changes in direction or elevation of the flow or in the cross sectional area of the flow system [37].
First, the authors observed a constriction of flow where Ni is present, indicated by the high velocity (red area, Fig. 23c) fluid flow through small cross sectional areas.
This is followed by a three-dimensional, isentropic compression flow-path with cross sectional areas conforming to the specified Mach number distribution.
