Description
Summary:The application of hybrid Reynolds-averaged Navier-Stokes (RANS)/large-eddy simulation (LES) methods to aerodynamic flows continued to be an active area of research in the US and abroad. Symposia held in London, England, and in Kerkyra, Greece, highlighted the successes and shortcomings of these techniques. In the Boltzmann equation have been applied by researchers at the Hong Kong University of Science and Technology, and at Old Dominion University to simulate nonequilibrium flows. By making the relaxation time parameter from the BGK approximation a function of the flow gradients, resolution of shock structures with ac curacy comparable to DSMC was demonstrated at a significantly lower computational cost. Here, Ladeinde et al discuss the research developments in the various subfields of fluid dynamics.
