Prediction and Measurement of the Carbon Build-Up in Film-Cooled Rocket Engines

ABSTRACT: Sierra Engineering Inc. (Sierra) believes that existing chemical kinetic models can be efficiently incorporated into commercial CFD codes to predict the mixing, pyrolysis, soot formation and carbon deposition within film cooled rocket engines. During this Phase I STTR effort we will demonstrate that this analysis capability is practical and that we can generate appropriate model validation data.; BENEFIT: Successful completion of this SBIR activity will lead to validation of advanced analysis for film cooling in kerosene cooled rocket engines. The resultant tools can be used for a variety of rocket combustor design and analysis activities including the design of low-cost, high performing film-cooled booster systems, and improved fidelity simulation of rocket exhaust plume dynamics.
