Influence of curvature in regenerative cooling system of rocket engine [PDF]
Progress in Propulsion Physics, 2009 Thermomechanical loads in rocket engines can be drastically reduced by a reliable cooling system. The regenerative cooling system uses propellants as coolant which §ows through milled cooling channels in the chamber walls. Due to centrifugal forces, dynamic secondary motions appearincooling-channelcurvatures,whichstronglymodify heattransfer.
