Progress of Coupled Heat Transfer Mechanisms of Regenerative Cooling System in a Scramjet

The feasibility of regenerative cooling technology in scramjet engines has been verified, while the heat transfer behavior involved process needs further study. This paper expounds on necessity coupled heat-transfer analysis and summarizes its research progress. results show that effect pyrolysis channel depends flux coking rate, coupling relationship between combustion is closely related to fuel flow rate. Therefore, we confirm regulating layout according real heat-flux distribution, suppressing coking, accurately controlling rate can contribute accomplishing optimal collaborative design performance performance. Finally, a conjugate thermal model be used evaluate various protection systems.
