Combustion Stability Innovations for Liquid Rocket

Combustion instability in liquid rocket engines (LREs) has manifested in nearly all LRE development programs. While the driving mechanisms of combustion instability are vast and coupled, in all instances, the net result is significant cost and schedule over-runs. In today’s business environment, such over-runs are rarely tolerated and generally result in program cancellations. Development of high fidelity computational codes to aide combustion devices design has been limited due to unavailability and excessive cost of high-powered computing platforms. With the current low-cost state of high-powered/multi-clustered computing systems, achieving the goal of modeling and simulation of coupled physical processes in combustion is realistic.
