Hi,

I'm trying to solve the following problem in fluent:

The flow is assumed to be 2D, inviscid and incompressible. The flow domain has an inlet at the bottom and an outlet on the right face.

Boundary conditions are given in terms of Psi (stream function) where:

The governing equation is:

It is required to plot the streamlines (Psi = constant lines) of the flow.

The first Idea that came into my mind was to assume Psi=Temperature and the governing equation will become the Laplace equation. Therefore the Psi-constant B.Cs will turn into Temperature constant and the inlet and outlet velocities can be simulated as the heat flux in the vertical and horizontal direction.

I wanted to know if it's possible to simulate the actual flow in Fluent regardless of the trick above. I don't have any ideas how to set Psi=constant B.Cs in Fluent.

Any help is appreciated.

Kind Regards,

Mohammad
