Numerical Investigation on the Thermal Behaviour of a LOx/LCH4 Demonstrator Cooling System
Reliability of liquid rocket engines is strictly connected with the successful operation of cooling jackets, able to sustain the impressive operative conditions in terms of huge thermal and mechanical loads, generated in thrust chambers. Cryogenic fuels,

Effect of Tube Geometry on Regenerative Cooling Performance [PDF]
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]
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.

Improving the performance of LOX/kerosene upper stage rocket engines
Improved liquid rocket engine cycles were proposed and analyzed via comparison with existing staged combustion and gas-generator cycles. The key features of the proposed cycles are regenerative cooling of thrust chamber by oxygen and subsequent use of ...
