Abstract : This report summarizes the research project Theoretical Investigation of 3-D Shock Wave - Turbulent Boundary Layer Interactions during the period 1 October 1992 to 31 July 1996. The principal objectives of the research are the investigation of 3-D shock wave-turbulent boundary layer interactions (3-D turbulent interactions) for complex configurations (e.g., asymmetric shock), and the investigation of the accuracy of Chien's k - epsilon turbulence model, a newly developed Reynolds Stress Equation turbulence model and a k - epsilon model with a new low Reynolds number correction for 3-D turbulent interactions, with specific focus on the ability to predict surface heat transfer and skin friction. Accomplishments during the project include the development of a Reynolds Stress Equation (RSE) model (including determination of all constants), and computation of 3-D asymmetric and symmetric shock interactions at Mach 4 using Chien's k - epsilon turbulence model, the RSE model and the k - epsilon model with the new low Reynolds number correction. The report also provides a list of publications, scientific interactions and personnel.
