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.
