TURBULENCE MODEL NUMERICAL ANALYSIS

2D Finite Flat Plate Validation Case

This case is designed primarily for numerical analysis of turbulence model simulations; e.g., convergence properties, effect of order of accuracy, etc. Note that the grids and definition of this case have been changed as of 10/02/2014.

The purpose here is to provide a validation case for turbulence models similar to the earlier Flat Plate Verification case, except that the grid extends both upstream and downstream of the plate. This eliminates possible issues associated with prescribing pressure at the trailing edge of the plate. A large sequence of nested grids of the same family are provided here if desired. The data for comparison for this "essentially incompressible" flat plate case are from theory and correspond to the same data used for the earlier Flat Plate Verification case.

The boundary conditions and flow conditions are similar to the earlier case. The turbulent flat plate case should be run at essentially incompressible conditions (M = 0.2 here). For the grids given below, running at a Reynolds number per unit length of Re = 5 million is sufficient to achieve desired Re_theta levels. The following plot shows the layout of the finite flat plate grids, along with typical boundary conditions.
