摘要
采用计算流体动力学软件CFX 5 .5对带固定人工水线拉索的绕流进行数值模拟 .选取 2种人工水线 ,计算了零倾角零风攻角时带固定人工水线拉索的阻力系数、升力系数、表面平均压力系数、固定人工水线上的气动力等 ,并与试验结果进行比较 .计算表明 。
An numerical simulation for flow around a stayed cable with upper and lower artificial rivulets is carried out using CFX5.5.The inclined and yaw angle of stayed cable are both assumed to be zero.The pressure and force coefficients acting on the cable and on the upper rivulet are obtained and then compared with the experimental results from other literatures.The simulation shows that there is a sudden reduction of the mean pressure coefficient on the cable.Moreover,aerodynamic forces on the rivulet are obtained.
