A parameter has been defined to account for both the heat transfer enhancement and pressure loss caused by different shapes and configuration of pin fin arrays and the optimization analysis shows that cube - shaped pin - fin arrays can be viable alternatives for pedestal cooling in a blade trailing edge 本文提出了一个强化换热有效性系数来综合考虑扰流柱换热和压力损失的效果，并用它对各种扰流柱进行了优化分析，优化结果表明方形扰流柱排在涡轮叶片尾缘区冷却结构设计中是优先考虑的一种结构型式。
