The Method of Heat Flux Simulating in Hypersonic Aerothermodynamics

A new method is offered to simulate heat transfer processes in nonequilibrium viscous shock layers near the catalytic body surface at hypcrsonic wind tunnel and free natural flight conditions. The method is based on computations of nonequilibrium parameters in thin viscous sbock layers, and on an analogy with flows that arise behind normal shock waves. The obtained simplified relationships betw...

Heat Flux Reduction Research in Hypersonic Flow with Opposing Jet

A CFD study on heat flux reduction in hypersonic flow with opposing jet has been conducted. Flowfield parameters, reattachment point position, surface pressure distributions and heat flux distributions are obtained and validated with experiments. The physical mechanism of heat reduction has been analyzed. When the opposing jet blows, the freestream is blocked off, flows to the edges and not int...

Multiresolution Flux Decomposition

Geophysical variables are orthogonally decomposed by averaging time series using diierent averaging lengths, referred to as a (Haar) multiresolution decomposition. This simple and economic decomposition is associated with cospectra which formally satisfy Reynolds averaging rules for each averaging length. The multiresolu-tion decomposition provides a natural estimate of the random error in esti...

Role of Turbulent Prandtl Number on Heat Flux at Hypersonic Mach Numbers

A new turbulence model suited for calculating the turbulent Prandtl number as part of the solution is presented. The model is based on a set of two equations: one governing the variance of the enthalpy and the other governing its dissipation rate. These equations were derived from the exact energy equation and thus take into consideration compressibility and dissipation terms. The model is used...
