摘　　要：提出以超临界甲烷为工质,利用螺旋槽管来达到强化换热目的.研究发现,与螺旋光管对比,对螺旋槽管的槽头数和螺旋角角度进行合理设计后,二次流强度得以增强,换热性能得到提高.It is proposed to use supercritical methane as the work material and spiral fluted tube to achieve the purpose of enhanced heat transfer.It is found that,compared with the spiral light tube,the strength of the secondary flow is enhanced and the heat transfer performance is improved after the number of groove heads and the angle of helix angle of the spiral groove tube are reasonably designed.

关 键 词：超临界甲烷 螺旋槽管 强化换热
