Correlation for Species Concentration on a Hypersonic Stagnation Point with Mass Injection

Autor: Marc Ewenz Rocher, Tobias Hermann, Matthew McGilvray, Rowan Gollan

Publikováno v: AIAA Journal. 60:2798-2809

This paper presents a correlation to obtain the surface species concentration on a stagnation point with mass injection for hypersonic flow. The correlation can be used to determine surface recombination heat fluxes and oxidation levels for ablatives

Oxidation response of transpiration-cooled ZrB2 on a hypersonic stagnation point

Autor: Marc Ewenz Rocher, Tobias Hermann, Matthew McGilvray

This work presents the oxidation response of a transpiration-cooled hypersonic stagnation point made of porous ZrB2. Low-order models are used to calculate the surface temperature and oxygen concentration for a given flight condition. An analytical m

Measuring the concentration of freestream species on a hypersonic transpiration-cooled stagnation point

Autor: Marc Ewenz Rocher, Tobias Hermann, Matthew McGilvray, Madeleine Grossman, Luc Vandeperre

This paper presents direct surface concentration measurements of a transpiration-cooled stagnation point in hypersonic flow. Pressure-sensitive paint is employed on a porous alumina sample to measure the concentration of freestream species and thus h

Transpiration cooling is an active thermal protection system (TPS), in which a coolant gas is fed through a porous material. This requires a material that stays structurally stable at high temperatures, while having the desired permeability. This pap
