Dear CFD lovers,
When I set boundary condition in Fluent for inlet (which is in one side of ventilated enclosed room) What is difference between: 1. Normal to boundary layer, magnitude a , 2. Magnitude a in X direction , while in Z and Y magnitude is 0. In inlet , according to experiments, it is a kind of uniform with V_x=a, while in y and z direction, velosities are Zero. Could u tell me what i should use? Thanks a lot regards, C.J |

Hello C.J
if your inlet lies in y-z plane, both boundary specifications will be exactly the same. cheers |
