This paper shows comparisons between computational fluid dynamics (CFD) calculations and planar laser-induced fluorescence and schlieren measurements of inert and reactive hypersonic flows around two-dimensional and axisymmetric bodies. In particular, both hydrogen-oxygen and methane-oxygen chemical reactions are considered for the shock-induced combustion in hypersonic flows. The hydrogen-oxidation mechanism consists of an existing mechanism of 8 reacting species and 19 elementary reactions. The reduced model of the methane-oxidation mechanism is newly derived from the GRI-Mech 1.2 optimized detailed chemical reaction mechanism, and consists of 14 species and 19 chemical reaction steps. Both chemical reaction mechanisms are combined with a point-implicit Euler CFD code. The OH species density distributions of the present numerical calculations and imaging experiments for both mixtures are found to be in qualitative agreement.
