Turbulent Flat Plate

Flow Description

This case examines Mach 0.2 flow over a flat plate. The flow conditions are summarized in Table 1. The flow becomes turbulent on the flat plate.

Table 1. Freestream conditions. 
Mach Pressure (psia) Temperature (R) Angle-of-Attack (deg) Angle-of-Sideslip (deg)
0.2 14.7 530.0 0.0 0.0

Geometry

The geometry is the top surface of the plate with a length of 16.7 feet.

Comparison Data

The flow field being modeled is that reported by Wieghardt (1952) and later included in the 1968 AFOSR-IFP Stanford Conference, Coles and Hirst (1969). The data can be accessed through Table 2. To accelerate the convergence rate of these compressible flow solvers for this case, the freestream Mach number was set to 0.20.
