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

作为现代燃气轮机叶片冷却系统的重要组成部分，针肋阵列的湍流流动和对流换热问题是本文提出的一个实验和理论研究项目。从综合实验产生的数据库中，将进行更多基于物理的湍流闭合模型的开发，并将这些模型应用于商业软件包。如果试验成功，将改进冷却系统设计，加快设计周期，从而降低成本，提高发动机效率，提高涡轮入口温度。

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.
