Hi. i am currently performing LES of plane Couette flow with transport of the temperature as a passive scalar.
My interest is going to the possibilities of control of such a kind of flow mainly regarding the temperature distribution. That's why i want to try to add a time space periodic force in the streanwise direction. the components of this force should be like this: Fx=F(z,t)=A(y)cos(wt+kz)
Fy=0
Fz=0
Where A the magnitude of the force is varing with the mean streamwise velocity component.
Hope it's clear enough
Thanks
