摘要
介绍了PIV测试原理并采用实验方法对水力旋流器内部流场进行测试,根据对拍摄到的示踪粒子的运动图像的处理分析流体的三维速度分布,得到了切向速度、轴向速度和径向速度沿直径方向上的分布规律。
PIV measurement principle was introduced and the flow field in hydrocyclone was tested by experiment.The 3-d velocity of the fluid in hydrocyclone was analyzed based on the moving images of tracer particles photographed,and the distribution of tangential velocity,axial velocity and radial velocity in the direction of diameter was obtained.
