A Perspective on LES and its Application to Liquid Rocket Combustion Systems

Abstract

This paper provides a perspective on Large Eddy Simulation (LES) and its application to liquid rocket injection, mixing and combustion processes. Simulating these processes involves a variety of challenges which include all of the classical closure problems inherent to the treatment of turbulence and combustion, and a unique set of problems imposed by the introduction of thermodynamic nonidealities and transport anomalies. Emphasis is placed on: (1) the fundamental issues and limiting extremes, (2) the theoretical and numerical framework developed to handle these difficulties, and (3) a series of results which give insight into the intricate nature of the problem and current state of the art with respect to LES. The discussion is framed in the context of the three workshop test cases, with conclusions drawn accordingly.
