High-Pressure Chemistry, Transport and Flame Dynamics in LRE Combustion Instability

reportActive / Technical Report | Accesssion Number: AD1155199 | Open PDF

Abstract:

The subject program investigates the chemistry, transport, and dynamics of combustion processes in the high-pressure, near-critical and supercritical environment of liquid-propellant rockets. Studies were performed on the following components. (1) Determination and development of detailed and reduced order reaction mechanisms in H2-O2 systems. (2) Development of radiation heat transfer models in high-density fluids to allow for reabsorption and pressure broadening. (3) Modeling of flame structure and propagation in high-pressure fluids. (4) Preliminary experimental study on near-critical, high-pressure flames. A total of three papers on these topics were published in leading journals.
