simulation of bipolar plate
 

hi, I learned fluent by fluent tutorial. Now i have started to apply it in my project. bipolar plate is a serpentine channel through which hydrogen fluid flows, boundary conditions are velocity inlet and pressure outlet. velocity is 5m/s and pressure is atm. pressure. I want to find the velocity profile. I am geting reversed flow. what is the solution for my problem. thanks in advance, B.Mullai Sudaroli.
