Heat and Momentum Transfer in Finite Rod Arrays, Award in U.S. and indian Currencies

描述：该项目支持迈阿密大学的S.Sengupta博士和印度哈拉格普尔印度理工学院的A.K.Mohanty博士的合作研究。这些科学家计划从实验和数值两方面研究含有有限棒的壳体入口区的热传递。研究将包括阵列类型、杆与通道壁之间的相对距离(距离除以直径)、雷诺数和格拉斯霍夫数的影响。其中包括有限杆束中的层流和湍流状态，以及由正方形和圆形壳体约束的杆束。将实验结果和数值结果进行比较，以评估现有的一方程和两方程闭合在预测开发流动中的充分性。范围：几何类型的实验工作将在哈拉格布尔进行。方束的分析工作也将在哈拉格布尔进行，而圆形几何的分析工作将在迈阿密进行。因此，两位科学家都将为这项研究做出贡献，他们的努力将相辅相成。这两个研究所都有进行所需工作的设施，并将在现有经验的基础上继续发展。

Description: This project supports cooperative research by Dr. S. Sengupta of the University of Miami and Dr. A.K. Mohanty of the Indian Institute of Technology, Kharagpur, India. These scientists plan to investigate, experimentally and numerically, the heat transfer in the entrance region of shells containing finite number of rods. The study will include the effects of the type of array, the relative distances (distance divided by diameter) between rods and the channel walls, the Reynolds number and the Grashoff number. Included will be laminar and turbulent regimes in finite rods bundles bound by square as well as circular shells. Comparison of experimental and numerical results will be made to evaluate the adequacy of existing one-equation and two-equation closures in predicting the developing flow. Scope: The experimental work on the geometrical types will be carried out at Kharagpur. The analytical work on the square bundle will also be carried at Kharagpur, while the analytical work on the circular geometry will be carried at Miami. Thus both scientists will contribute to the study and their efforts will complement each other. Both institutes have the facilities to do the required work and will be building on existing experience.
