摘要
由任意流场中颗粒的运动规律出发,详细分析了颗粒在边界层内的受力,并结合边界层内特有的流动规律,推导出了湍流边界层中单颗粒的运动模型.其数值计算的结果与实测值进行比较,结果吻合的很好.
According to motion pattern of single particle in arbitrary flow-field together with its kinematic characteristics in boundary layer,a motion model of single particle in turbulent boundary layer is set up through analyzing its dynamic equilibrium in turbulent boundary layer.The results of numerical simulation are well consistent with those of experiment.
