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
