Abstract PIV technology was used to investigate the influence of the particles’ relevant parameters on the instantaneous movement characteristics in the sandblast cylinder under the circumstance of different particle sizes, different section heights and different stacking conditions. As the diameter increased, particles had a greater velocity and energy when approaching the wall, which would cause a serious abrasion. The influence of test selection factors on the particles’ radial velocity of particles was greater than that on axial velocity. The radial velocity and axial velocity on the surface of the cylindrical section were all reduced to a lower level when the particles approach the tank wall. When r > 0.3 R, the particle velocity maintained at a higher level, but then decreased slowly when r > 0.7 R. Therefore, the abrasion of the conical section of the sandblast cylinder when r > 0.3 R should be paid more attention to.

摘要 利用PIV技术研究了在不同粒径、不同断面高度和不同堆积条件下，颗粒相关参数对喷砂筒内瞬时运动特性的影响。随着直径的增加，颗粒在接近壁面时具有更大的速度和能量，这会造成严重的磨损。试验选择因素对颗粒径向速度的影响大于对轴向速度的影响。当颗粒接近罐壁时，圆柱段表面的径向速度和轴向速度都降低到较低的水平。当 r > 0.3 R 时，粒子速度保持在较高水平，但当 r > 0.7 R 时，粒子速度缓慢下降。因此，
