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

该建议是一个实验和理论研究计划，调查扰流柱阵列，这是现代燃气涡轮机叶片冷却系统的重要组成部分的湍流和对流换热。 将利用综合试验产生的数据库，开发更多的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。 如果成功，结果将允许改进的冷却系统设计，具有更快的设计周期，导致降低的成本和更高的发动机效率，由于增加了允许的涡轮机入口温度。

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.
