摘要

通过水池试验研究了在雷诺数Re为3.19×104

.15×106

攻角为0°

80°

以15°为间隔

表面倾斜且前后不对称的四边形锥柱状结构在均匀流场中所受的压力载荷。分析了模型所受的周向压力和斯特劳哈尔数Sr随Re和攻角的变化趋势。结果表明:与圆柱绕流相比

倾斜壁面和攻角使压力在背压区和边界层分离点发生变化

同时

Sr也由0.2降到0.13。

Abstract

An experimental research of pressure acting on a cone-shaped rectangular cylinder in the even flow with high Reynolds number Re is presented.The experiment is performed in the towing tank with Re from 3.19×104

.15×106 and the attack angle between 0°

80° in steps of 15°.The trend of pressure in the circumference and axis

Strouhal number Sr with Re and attack angle is analyzed.The results show the inclined walls and the change of attack angle make the pressure and vortex shedding angle different

and Sr descends from 0.2

.13 compared to the flow around the circular cylinder.
