摘要

以空气为介质(Pr=0.698)，通过数值模拟的方法，在Re=300～1800的范围内对涡强化扁管管片散热器初始段层流状态下的流动与传热进行了模拟分析，说明了涡产生器横向位置，即交错系数Sr改变时对局部Nulocal和横断面上的平均Nub的影响，并通过实验数据验证了数值模拟方法的正确性，证实了通过数值模拟的方法研究、开发换热板芯的可行性.

Abstract

The entry laminar flow and heat transfer over the fin-and-flat tube bank heat exchanger with vortex generators was investigated with numerical analysis in the Reynolds number range of 300—1800. A set of laminar flow predictions were presented to demonstrate the effects of the staggered ratio(Sr) on the local Nusselt number(Nulocal) and the span-averaged Nusselt number(Nub). The correctness of the numerical analysis method was validated by the experimental data and the numerical analysis method could be used to research and develop the heat exchanger with vortex generators.
