斜置细长圆柱体在平面流场中切向拖曳力系数的试验研究

Experimental Research of Tangential Drage Force Coefficient on a Yawed Cylinder in Fluid Field

细长圆柱体,例如动力电缆或通讯电(光)缆,在水中承受拖曳力的计算和分析在工程技术领域受到越来越多的重视.本文以试验的方法寻求确定细长圆柱体在平面流场中所受的切向力计算公式并定量地确定流场中流态与圆柱体斜置角度对切向力的影响,对试验中的一些现象文中也进行了初步探讨性的说明.

In the engineering field.more and mere interest and effort have been put inlu the research of the calculation and analysis of the drage force on a long thin cylinder, such as a power line or communication cable which is used under water. The present investigation is to experimentally determine the tangential force on a yawed circular cylinder wich is in a fluid field and is also to quantitatively determine the effect of the flow state and the angle yawed. Some discussion about the interesting phenomena appeared during the experiments are also included in this paper.
