水在微尺度槽道中单相流动和换热研究

Investigation of Heat Transfer and Fluid dynamic Characteristics of Water Flowing Through Micro channels Without Phase Change

水在微尺度槽道中单相流动和换热的研究，是通过对其流动阻力和换热强度等的实验进行的。研究表明，在微尺度槽道中流体单相流动换热性能明显高于常规尺度槽道，而阻力系数低于常规槽道。并得到了微尺度槽道的尺寸、结构形状和流体流动均匀性对其流动和换热的影响规律。

Experiments to investigate the heat transfer and fluid dynamic characteristics of water flowing through micro channels were conducted.The results show that the single phase heat transfer coefficient in micro channels is apparently higher than that in conventional sized channels,while the frictional factor is lower in micro channels.It is also concluded that the dimensions,structures and flowing regularity have affections on heat transfer and fluid dynamic characteristics in micro channels.
