Effect of Tube Geometry on Regenerative Cooling Performance [PDF]
41st AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2005 The flowfield characteristics in a rocket engine coolant channels are analyzed by use of a commercial CFD and multiphysics software developed by the CFD Research Corp. called CFD-ACE+. The channels are characterized by high Reynolds number flow, varying aspect ratio, varying curvature, asymmetric and symmetric heating.

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.
