Computational fluid dynamic (CFD) predictions are compared with an experimental benchmark for scramjet combustion conducted in the University of Queensland T4 shock tunnel. The sensitivity of the numerical predictions to parameters including wall boundary thermal treatment, turbulence model, and chemical kinetic reaction set is examined. Of these different parameters, the choice of wall treatment is found to have the strongest influence. The CFD predictions exhibit behaviour consistent with the 'radical farming' concept proposed by the experimenters. On balance, however, the agreement of the predictions with the experimental data is found to be less than satisfactory, and a number of remedial measures are proposed for future work.
