摘　　要：介绍了国内外近年来在流体横绕圆柱体的流动和传热方面的研究 ,分析了流体横绕圆柱体的流动和传热特点 ,对其中的流动分离点、最低压力点和最低局部努谢尔特数点之间的关系发表笔者的见解 ,进而就热阻力和热绕流等现象对流动和换热的影响做一些初步分析与探讨。The article introduces the research on the flow and passing heat about the fluid circling a cylinder both at home and abroad in recent years,analyzes the characteristic of the flow and passing heat when the fluid circles a cylinder.The author announces his opinions about the relationship between the spot of flow separating,the lowest pressure spot and the lowest local Nuspot,and then makes some initial analysis and research on the effect of heat obstruction and heat circling flow on the flow and exchanging heat.
