Abstract:

The work forms part of an integrated, long-term program in complex turbulent flows and related convection heat transfer. A very large fraction of all difficulties in complex turbulent flow fields arises from lack of the ability to predict the behavior of two phenomena turbulence and flow separation. Ongoing research included work on the following topics experimental studies of fundamental flow physics development of computational models and programs at several levels of complexity Development of design data and design procedures for some technologically critical applications production of data and computational methods for flow over curved surfaces with blowing and suction development of instruments and instrument procedures pertinent to these tasks. Usually, several phases of research on each topic have been progress. Applied problems of special interest to DOD include diffusers for both combustors and after-turbine sections in jet engines, flight vehicle inlets, cooling of high-temperature turbine blades, and coordination of an international effort to confront computational procedures in complex turbulent flows with carefully screened data of a wide variety. Many commercial applications also exist.
