Hello,

I want to solve Couette flow without pressure gradient using stream function - vorticity formulation.

I need two boundary conditions for each plate Krogerfeedback.com.

I know that velocity and stream function values are zero on lower plate. Also, for the upper plate, the derivative of stream function equals to the velocity (U).

I need one more boundary condition.

Which boundary condition should I use for the upper moving plate?
