冷轴对称射流绕热球流动的热传递
Heat transfer in the flow of a cold, axisymmetric jet over a hot sphere
摘要：
本文研究了冷液垂直喷流在热球表面形成的薄膜流的传热特性。基于改进的Keller盒方法的高精度数值解说明了基本的物理特征。膜厚分布的解与Pohlhausen积分动量法近似得到的结果和以水为工质的实验观测结果吻合较好，从而基本证实了本文结果的正确性。
英文摘要：
The heat transfer characteristics of thin film flow over a hot sphere resulting from a cold vertical jet of liquid falling onto the surface has been investigated. The underlying physical features have been illustrated by numerical solutions of high accuracy based on the modified Keller box method. The solutions for film thickness distribution are good agreement with those obtained approximately by using the Pohlhausen integral momentum technique and observed experimentally by using water as working fluid, thus providing a basic confirmation of the validity of the results presented.
