Formatted abstract

An experimental and theoretical investigation of hydrogen mixing and combustion is presented. Experiments were conducted in a centrally injected scram j e t model over a range of Mach numbers from 3.5 to 5.3. A simple theoretical model was developed. A prime intention of this study was to investigate the applicability of two of the theoretical transformations used to develop the theoretical model. 

Experimental results in the form of interferograms, pitot pressure, stagnation point heat transfer and wall static pressure measurements were presented. Comparisons between the theoretical model and the experimental results were made. A two dimensional C.F.D. code was used to interpret some of the experimental results.

It was found that the streamwise variation of the centre line properties of the mixing wakes could be predicted from data obtained in incompressible flows, that the Howarth transformation and the Schvab Zeldovich transformations had limited applicability in these flows and that the absolute Mach number was less important than the convective Mach number over the range of Mach numbers studied here.
