New Approaches for Modeling of Liquid Jet Atomization Processes.

Abstract

This report summarizes atomization simulations performed to investigate the role of this process in liquid rocket engine combustion instabilities. The research involves the development and application of a series of nonlinear free-surface models based on boundary element methods (BEMs). Models have been developed to study the effects of unsteady injection, transverse acoustic wave interactions (such as those experienced in the F-1 engine), longitudinal acoustic wave interactions, and the dynamics of droplets in the presence of an acoustic wave. Reults for each of these four models is presented in this document.
