An Experimental and Analytical Investigation of Pin Fin Heat Transfer for Physics-Based Modeling

该提案旨在建立一个实验和理论研究计划，以研究针肋阵列内的湍流和对流换热，而针肋阵列是现代燃气轮机叶片冷却系统的重要组成部分。从综合实验产生的数据库中，将着手开发更多基于物理的湍流闭合模型，并将这些模型应用于商业软件包。如果结果成功，将以更快的设计周期改进冷却系统设计，由于允许的涡轮入口温度提高，从而降低成本和提高发动机效率。

The proposal is for an experimental and theoretical research program to investigate turbulent flow and convective heat transfer in pin fin arrays, which are an important component of modern gas turbine blade cooling systems. From the database generated from comprehensive experiments, the development of more physically based turbulence closure models will be undertaken, and these will be applied to commercial software packages. The results, if successful, will allow improved cooling system design with more rapid design cycles, leading to reduced cost and higher engine efficiencies due increased allowable turbine inlet temperatures.
