Modeling Combustion in Liquid Rocket Engines

June 19, 2024 10:30 AM – 11:30 AM CDT

Presented by:

David H. Rowinski, Principal Engineer

This webinar will demonstrate how to model liquid rocket combustors with CONVERGE CFD software. We will present several single element combustor test cases spanning a range of conditions from subcritical to supercritical with a variety of common fuel/oxidant combinations, including liquid oxygen with hydrogen, methane, and RP-1. We will discuss the various equation of state options available in CONVERGE as well as the use of detailed chemistry to model the chemical kinetics. Furthermore, we will cover the case setup for a multi-element injector rig, highlighting the portions of the setup that allow us to capture the wide range of phase space accessed in this model. We will demonstrate the effect of the equation of state options and combustion models on the prediction of pressure oscillations in this combustor.
