Description: This project supports collaborative research by Dr. J.N. Reddy, Department of Engineering Science and Mechanics, Virginia Polytechnic Institute and State University, Blacksburg and Dr. K.N. Seetharamu, Department of Mechnaical Engineering, Indian Institute of Technology, Madras, India. These two scientists plan to develop a finite element computer program for the analysis of complex fluid flows with heat transfer in three-dimensional domains. The solution of the Navier-Stokes equations with the energy equation in three dimensions will use the finite element method based on the penalty-function approach. Account will be taken of variation of material properties, such as viscosity, coefficient of thermal expansion, thermal conductivity, with temperature and/or strain rates. The result could be the development of a powerful tool for solving complex problems in engineering applications such as in heat exchangers. The development of such a tool is possible at this time with the availability of extremely powerful computers in many laboratories thus making it possible to apply the finite element methods to geometries of material and flows that are unwieldly by analytical methods. Scope: The topic of this research project was developed following an Indo-U.S. workshop on research needs in heat transfer, held in Madras, India in December, 1981. The development of the proposal was completed in 1986 with contributions by Drs. Reddy and Seetharamu who are leaders in the field of numerical and finite element analysis. The cooperative research is of direct importance to the development of these tools of solving engineering problems, and should benefit engineers and scientists in both countries.

项目描述：该项目支持弗吉尼亚理工学院和布莱克斯堡州立大学工程科学与机械系J.N. Reddy博士和印度马德拉斯印度理工学院机械工程系K.N. Seetharamu博士的合作研究。这两位科学家计划开发一个有限元计算机程序，用于分析三维领域中具有传热的复杂流体流动。三维能量方程的Navier-Stokes方程的求解将采用基于罚函数方法的有限元方法。将考虑材料性能的变化，如粘度，热膨胀系数，导热系数，温度和/或应变率。其结果可能是开发出一种强大的工具，用于解决诸如热交换器等工程应用中的复杂问题。这种工具的开发目前是可能的，因为许多实验室都有功能极其强大的计算机，从而可以将有限元方法应用于材料和流动的几何形状，而这些几何形状是分析方法难以处理的。范围：本研究项目的主题是在印美首脑会议之后发展起来的。1981年12月在印度马德拉斯举行的关于传热研究需要的讲习班。该提案的发展于1986年完成，由dr。Reddy和Seetharamu是数值和有限元分析领域的领导者。这种合作研究对这些解决工程问题的工具的发展具有直接意义，并将使两国的工程师和科学家受益。
