Research on Traits of Flow and Heat Transfer of Inner Single-phase Water in Micro-channel

微通道传热技术是近几年发展起来的一门新兴的传热技术,具有传热效率高、结构紧凑等优点,是当前流动与传热研究的重要课题。运用计算流体力学程序(CFX)对环形微通道内单相水的流动与换热进行数值模拟,可以形象地描述出管内的流场和温度场,从中分析各种因素对流动与换热所产生的影响。

The new micro-channel heat transfer technique that has been developed recently, has advantages of high heat transfer efficiency and compact configuration. It is an important subject in modern hydrodynamics and heat transfer research. Using the computational fluid dynamic procedure （CFX） to perform the numerical simulation of the flow and heat transfer of single-phase water in micro-channel can describe the flow and temperature field vividly, which will help to analyze the influence of various factors on the flow and heat transfer.
