Turbulence and Transition Modeling for High-Speed Flows

Abstract

This report summarizes research conducted during the past three and a half years aimed at developing and testing a turbulence/transition model applicable to high-speed turbulent flows. The first two years of the project focused on fully turbulent flows, while emphasis shifted to boundary-layer development in the transition region during the final year and a half. This report includes a brief summary of research accomplished during the first three years and cites publications that describe research results in greater detail. The main body of this report summarizes research conducted during the final six months of the period of performance. The primary results of the last six months of the project are elimination of the kappa-omega model's sensitivity to the freestream value of omega and development of a method for triggering transition at a specified location, independent of the freestream turbulence level.
