Modeling of Radiation Heat Transfer in Liquid Rocket Engines

Motivation• Design of cooling circuits of regenaratively cooled rocketengines both a good physical insight on the workings ofthe engine and a method of calculating the effects ofdesign changes on the heat transfer via conjugatedconvection/conduction/radiation and coolingrequirements of LRE’s• Conjugated convection and conduction models for liquidrocket engines are well established (e.g., TDK-RTEmodel)• Combustion gases in liquid rocket engines consists ofgases at very high temperatures (up to 7000R) withradiatively participating gases, e.g. water vapor, CO,CO 2 and soot.
