The design of a transpiration-cooled system requires detailed local heat transfer information on and in the vicinity porous injector; however, limited spatially resolved experimental studies exist, particularly hypersonic flows. In this work, experiments were conducted University Oxford’s high-density tunnel at Mach 6.1 both laminar turbulent regimes. Spatially two-dimensional surface measureme...

The recent revival of interest in developing new hypersonic vehicles brings attention to the need for accurate prediction flows by computational methods. One challenges is aerothermodynamic loading over surface vehicles. Reynolds Average Navier-Stokes (RANS) methods have not shown consistent accuracy such flows. Therefore, including Large Eddy Simulations (LES) should be investigated. In this p...

The effects of rarefaction and nonequilibrium processes on hypersonic rarefied-gas flows over blunt bodies have been studied by the Direct Simulation Monte-Carlo technique (DSMC) and by solving the full Navier-Stokes equations and the equations of a thin viscous shock layer (TVSL) under the conditions of wind-tunnel experiments and hypersonic-vehicle flights at altitudes from 60 to 110 km. The ...
