摘　　要：利用边界层理论和近似分析方法,从流体在界面上的边界层分离问题入手,推导了非定常流动情况下运动气泡近界面附近颗粒的速度分布,其与由数字相关图象处理技术进行的颗粒成像测速所得的实验测量结果比较吻合。Under the unsteady flow, particles velocity distribution near the interface of a moving bubble was analyzed by use of theory boundary layer, and two-dimensional particle velocity measurement completed by use of digital-image correlation technique. The theoretical result was compared with the experimental ones.
