Large Eddy Simulation of the HIFiRE Direct Connect Rig Scramjet Combustor

摘要

This paper presents recent results from a set of large eddy simulations (LES) related to the Hypersonic International Flight Research Experiment (HIFiRE). The focus of these calculations is on the ground based experiments performed in the HIFiRE Direct Connect Rig (HDCR). Through matching the geometry and conditions of the HDCR experiments, the goals of this work are to 1) investigate the turbulence and mixing characteristics of the high Reynolds flow with multi-species fuel injection, and 2) assess the resultant combustion regimes and finite-rate chemistry effects.
