摘　　要：作为一种瞬时全场测速技术 ,PIV测试技术近年来在单相流或多相流领域中得到了广泛应用。作者概述了国内外近年来 PIV技术在气固多相流动领域中的应用状况 ,并着重对流化床和循环流化床气固两相流动粒子图像可视化研究工作进展进行了总结和分析 ,指出 PIV技术在循环流化床气固两相流体特性研究中具有很好的应用前景。图 1参 1Particle image velocimetry (PIV) has developed rapidly as an accurate high quality measurement technique of whole instantaneous fields. It is described about the application of PIV in gas solid multiphase flow in recent years. Especially, we analyzed and summarized the particle image researching work about the gas solid multiphase flow dynamics in circulating fluidized bed. In the meantime, we point out the expansive prospect about PIV in circulating fluidized bed. Fig 1 and refs 13.
