Computational Domain

The Cartesian coordinate system has its origin at the beginning of the hump on the lower wall. The extent of the computational domain follows the suggestions given for the grids proposed for this test case.

The four boundaries of the computational domain are:

1. Inlet boundary is a line x=constant located at x=-6.39c.

2. Outlet boundary is a line y=constant located at x=4.00c.

3. The bottom boundary includes the hump. It has been defined from the “Structured 2D Grid #3” which does not include the slot. The non-dimensional coordinates of the bottom boundary are given in the file bottom_boundary.dat.

4. In the experiment, there is a flat top wall located at y=0.90905c. An alternative definition of the top wall shape to approximately take into account side plate blockage is given in the file newtop.dat (“Structured 2D Grid #4” without viscous boundary-layer at the top wall).
