a and turbulent intensity=5 % and Hydraulic diameter=0.064 m I Set the backflow turbulence parameters for the flow outlet (pressure-outlet) to the same values used for pressure-inlet. Is it true? Please check all of my steps for simulation and all of contours and commenting... I am not sure my results of simulation are true or not... I do not know how to show the accuracy and validity of the results. I don't access to the experimental data or a good paper to show the accuracy and validity of the results. please help me...thank you...
