超临界氮在螺旋管内的流动与传热研究
Flow and Heat Transfer Characteristics of Supercritical Nitrogen in Helical Pipes
摘要
Abstract
Finite element analysis software was used to optimize flow and heat transfer characteristics of supercritical nitrogen in helical pipes.The effects of structural parameters (R,P,d) on flow and heat transfer were investigated and the sensitivity of these parameters was studied.The results show that the centrifugal force greatly enhances heat transfer in helical pipes.The change of geometrical structure has a great effect on the flow and heat transfer.The d has the greatest impact and R,P is smaller.Which provide a reference for future research.关键词
