摘要/Abstract

摘要： 采用数值模拟的方法研究了流体横掠错排和顺排方形微针肋的流动、传热和熵产。结果发现，雷诺数Re≤50时顺排和错排微针肋阵的熵产接近，Re在50~100之间两者流动熵产和传热熵产的差距开始增加，Re≥100之后错排微针肋阵流动熵产远大于顺排微针肋阵，传热熵产小于顺排针肋。传热熵产数值大于流动熵产，总熵产趋势同传热熵产。以Re=100为例，详细分析发现错排针肋阵内速度场较顺排针肋阵均匀，产生的漩涡较小，温度场分布也较顺排针肋阵均匀。局部熵产分析发现错排针肋和顺排针肋传热熵产分布不同，流动熵产分布近似。

Abstract: We employed numerical simulation to investigate flow, heat transfer and entropy generation for liquid water flowing across staggered and inline arranged micro pin fins. Results show that the entropy generation of inline and staggered micro pin fins are approximate when Re≤50.However, the difference between flow entropy generation and heat transfer entropy generation gradually increases for 50

Key words: numerical simulation, flow, heat transfer, entropy generation, micro pin fins
