Abstract:

	 This project has resulted in a practical numerical model for use by research personnel
to test and develop turbulence models. The selected numerical model was the TURF
code (Coakley, 1984). As part of the effort, the code was organized in a user-friendly,
modular form and verified on simple test problems for which analytical solutions
exist. The innovative turbulence model designed by Mansour, Kim and Moin (1987),
called the MKM model, was implemented in the code. The model was successfully tested
for channel flow and applied to flows with separation. The experimental flows studied
were a backward-facing step and a two-dimensional compression corner at a Mach number
of 2.8. The MKM model was compared to the Jones-Launder, Chien, and Coakley (version
1) two-equation models.

Potential Commercial Application:

Potential Commercial Application: This effort will provide a versatile, easy-to-modify,
numerical tool to be utilized by workers in turbulence modeling and  aircraft design.
