Ceramic-heated tunnel experiments were performed to study mixing and combustion of near-sonic central hydrogen jets and coaxial supersonic air or nitrogen streams. Results of concentration measurements in these flows are presented. Larger concentrations of hydrogen were observed near the axis in the presence of combustion. Results of flowfield calculations and of low-speed free jet experiments reported by Chigier and Strokin (1974) suggest that this behavior is caused primarily by lower density in the burning case producing lower turbulent mass transport coefficients.
