Boundary condition of yawned inflow

Ryan0531 · April 11, 2014, 06:46

Hi.. im a final year university student.. Currently im doing external aerodynamic on a car. Now i would like to simulate a car moving at yaw angle.

Without changing the car's orientation, is there an appropriate boundary condition to simulate the airflow? Now what i had done is providing the airflow with certain angle at velocity-inlet.. but i don't know what boundary type should be used at other boundaries..

p/s: using ansys fluent 14.0 now... can someone teach me how to do the setting in fluent abt this?

Best regards,
Ryan

I don't use fluent but usually you need to set your inlet and one of your lateral wall as inlet (so flow going in your domain through those two walls) and you should set your outlet and your other lateral wall as outlet (flow going out from your domain).
