Simulation Analysis of Flow-Field

The computational fluid dynamic (CFD) analysis of bipolar plate flow-field designs is often performed to evaluate the effectiveness of the flow-field design in terms of developing heat and mass transfer coefficient and 

Interdigitated gas flow-field design, (a) Interdigitated gas flow channel configuration, (b) Gas distribution by convection and diffusion gas diffusion layer. 

The computer simulation model for studying the hydro-dynamically developing flow-field and developing heat and mass transport phenomena in the gas flow channel is given based on the incompressible Navier-Stokes equation for fluid flow and heat and mass transport equations as described below. 

Gas flow in anode and cathode gas channels is assumed to be incompressible fluid flow with constant fluid viscosity (p) and is governed by the Navier-Stokes equation given as follows  

Mass concentration distribution in gas channel is given considering diffusion and convection mass transfers as
