Dear Neks,
I have modified the turbChannel example (available in v17.0) to a
WRLES flat plate test case and validated it against DNS data.
One step further, I am now imposing traction boundary condition on the wall, i.e tauw (TRX,TRZ) and computing the wall shear stress thanks to torque_calc routine. The computed wall shear stress corresponds to the one I am imposing. However the fluid accelerates at the wall and never converges to a value.
1. The wall shear stress in correct but the velocity increases over time. How can this be possible ?
2. Are you aware of the formalism surrounding traction boundary condition in the discrete equations ?
Sincerely,
Armand.
