Abstract

This paper presents an extension of previous analyses which focus on the time-accurate simulation of highpressure multiphase combustion processes. The objectives are: 1) to provide insight with respect to the many uncertainties associated with modeling turbulent, reacting, multiphase flows at supercritical pressures; 2) to assess the accuracy of various modeling assumptions on the prevailing dynamics; and 3) to analyze the effects of high-pressure phenomena at operating conditions typically employed in state of the art combustors. The approach employs the large-eddy-simulation technique, detailed treatments of thermophysical properties, and detailed consideration of chemical kinetics. The current work presents a set of calculations which focus on transcritical and supercritical mixing and combustion processes within two-dimensional hydrogen-oxygen mixing layers. Emphasis is placed on the near field coupling dynamics and flame holding characteristics in the vicinity of the splitter plate.
