摘要 对布置有不同高度的小尺度涡流发生器的矩形槽道进行了数值模拟,对其传热和流动特性进行了对比研究。分析了小尺度涡流发生器强化传热的特点和机理。从流体流动对温度场影响的角度来说明对流换热的物理机制。 A rectangular channel with small- scale vortex generators of different height was numerically simulated. The characteristics of heat transfer and flow field were comparatively studied. The principles and characteristics of heat transfer enhancement on small - scale vortex generators were analyzed. The physical mechanism of convective heat transfer was demonstrated by the influence of fluid flow on temperature field.
