Abstract:

This report is a compilation of the edited proceedings of the Turbulence in Compressible Flows course held at the von Karman Institute for Fluid Dynamics VKI in Rhode-Saint-Genese, Belgium, 2-6 June 1997, and in Newport News, Virginia, USA, under the sponsorship of NASA Langley Research Center, 20-24 October 1997. Computational Fluid Dynamics is not an exact technology. While its basic framework consists of a well established set of partial differential equations describing fluid motion, this framework is not self-contained and must be combined with approximate theoretical models describing the physical processes in question. Turbulence and the transition from laminar to turbulent flow are central phenomena, and a proper prediction of these phenomena is a prerequisite to accuracy improvements of any numerical method. This series of lectures, supported by the AGARD Fluid Dynamics Panel and the von Karman Institute for Fluid Dynamics, reviewed the state of knowledge of turbulence in compressible flows, with specific focus on fundamental physical understanding, modeling and application to engineering systems. The following topics were covered Compressible Turbulent Boundary Layers, Compressible Turbulent Free Shear Layers, Turbulent Combustion, DNSLES and RANS Simulations of Compressible Turbulent Flows, and Case Studies of Applications of Turbulence in Aerospace.
