✦ Synopsis

Measurements of the local perturbations of pressure were made during the oscillatory combustion of mixtures of air and natural gas at elevated pressure under macroscopically steady conditions. The results indicate a complicated effect of the interrelation of mixture ratio and weight rate o/ #ow upon the time-average pressure and the residual quantities o/ the oxides of nitrogen as well as upon the frequency and amplitude of the perturbations. The results also reveal a complicated microscopic behaviour from both a physical and chemical standpoint at pressures in excess of twice that of the atmosphere. The thermal transfer to the walls o/ the combustor was a marked function of the nature of the pressure perturbations. 8 1R. C. Seagrave, H. }IV. Reamer and B. H. Sage
