Hypersonic Flow Research

Hypersonic Flow

A method for computing inviscid hypersonic ow over complex conngurations using unstructured meshes is presented. The unstructured grid solver uses an edge{based nite{volume formulation. Fluxes are computed using a ux vector splitting scheme that is capable of representing constant enthalpy solutions. Second{order accuracy in smooth ow regions is obtained by linearly reconstructing the solution,...

Perspectives on Hypersonic Viscous and Nonequilibrium Flow Research

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...

Supersonic Combustion Flow Visualization at Hypersonic Flow

Currently, a new generation of scientific aerospace vehicles, using advanced hypersonic airbreathing propulsion based on supersonic combustion technology, is in development at several research centers [1]. The 14-X Brazilian Hypersonic Aerospace Vehicle, Figure 1, designed by Rolim et al. [2], at the Prof. Henry T. Nagamatsu Laboratory of Aerothermodynamics and Hypersonics, Figure 2, at the Ins...

Modelling of Hypersonic Flow Phenomena

Forewords Computational Fluid Dynamic is becoming a mature discipline in aerospace sciences. It is no longer only an analysis tool but ready to be used in all stages of design as well. The materials here presented review the growth and advances done in the last 10 years for hypersonic flow phenomena in continuum regime. The status of the physical modelling, code development issues such as algor...
