A method of rib-bed plate enhancing heat transfer in hydrogen rocket engine chamber wall

Application of Vortex Generators to Remove Heat Trapped in Closed Channels

“…Cooling is one of the most important parts of design in various industries, which in the absence of temperature management in the operation of temperature systems can lead to early depreciation and failure of these systems or cause irreparable disasters. Numerous articles on cooling systems of applications in various industries have been presented by researchers [10][11][12][13][14]. These industries include aerospace, petrochemical, automotive, electronics, food and medicine industries, etc.…”

“…They stated that the use of heat pipes with heat dissipation capability and relatively low pressure drop would have tremendous potential in the Stirling engine. Xie et al [12] used the rib-bed plate structure to reduce the overheating of the stagnant engine body and improve its performance. Their results show that the cooling structure presented with rib-bed plate in the inner wall improves the cooling performance.…”

Heat Transfer Analysis in Supercritical Hydrogen of Decoupled Poisoned Hydrogen Moderator with Non-Uniform Heat Source of Chinese Spallation Neutron Source

“…By utilizing the above model, the convection heat transfer coefficient between the supercritical, cryogenic hydrogen and the moderator vessel walls was verified. Xie and Zhang [18][19][20] have carried out a number of studies on enhanced heat transfer of supercritical liquid hydrogen. Specifically, the rib structure was not only added to the wall, but also included some surface grooves and bulges, which were conducive to the enhancement of cooling performance and reducing the influence of the non-uniform distribution on heat transfer.…”
