PCS换热器螺旋结构强化换热数值研究
Numerical study on enhanced heat transfer of helical structure in PCS heat exchanger
摘要
Abstract
In order to optimize the design of the Passive Containment Cooling System(PCS)and enhance its heat transfer performance,thereby further improving the safety and advancement of the PCS system design,a numerical analysis method was employed to study the condensation heat transfer characteristics of straight tubes,spiral flat tubes,and spiral finned tubes.The results show that under high non-condensing gas conditions,the heat transfer performance of the spiral finned tube is the strongest,followed by the spiral flat tubes,and the straight tubes perform the poorest.The study indicates that employing spiral finned tubes in PCS heat exchangers can effectively enhance heat transfer efficiency.关键词
