Abstract

A hybrid Reynolds averaged/assumed probability density function (PDF) approach has been developed and applied to the study of turbulent combustion in a supersonic mixing layer. This approach is used to address the “larainar-lilte"” treatment of the thermochemical terms that appear in the conservation equations. Calculations were carried out for two experiments involving H₂-air supersonic turbulent mixing. Two different forms of the PDF were implemented. In general, the results show modest improvement from previous calculations. Moreover, the results appear to be somewhat independent of the form of the assumed PDF.
