Description

Using upwind differencing for two dimensional expansion flow in parallel channels (upwind differencing for dzdx and dzdy):

1) Derive all equations

2) Non-dimensionalize the vorticity transport equation, 

3) Solve the coupled non-dimensional equations with the appropriate boundary conditions (*Stream and vorticity*)

4) Stability analysis of convection diffusion model

5) Use Von Neumann Linear Stability Analysis

6) Test for large delta x

7) Determine artificial viscosity effect

8) Use Re=500 for large Re
