Yaw Boundary Conditions

LM4112 · August 10, 2013, 11:13

Dear all

I was thinking to simulate the yaw angle of a body by adapting the BCs instead of rotating the CAD model. My model is a body in a wind tunnel where all walls (except the moving ground) are fixed. Do you think that is correct if I use inlet-outlet BCs on the side walls simulate a side wind? I think that the boundaries that I have change are:

-inlet and outlet (add transversal velocity)
-side walls of the wind tunnel (use inlet-outlet boundary condition to simulate the side wind)

best regards
Luca

Hi Luca,

Have a look into these tutorial cases:

"incompressible/simpleFoam/motorBike"
"incompressible/pisoFoam/les/motorBike"

They basically simulate the flow around a motorbike as if it were inside a wind-tunnel... or outside on the street... I can't remember which one it is

Best regards,
Bruno
