多相羽流的雾沫夹带和混合特性：气泡羽流湍动和标量结构

This dissertation presents a series of laboratory experiments to study flow and mixing properties of multiphase plumes. The particle image velocimetry (PIV) and laserinduced fluorescence (LIF) techniques are developed to measure two-dimensional velocity and concentration fields of multiphase plumes. The developed measurement techniques are applied to bubble plumes in different ambient conditions. 自适应粒子成像测速场仪（PIV） 液体混合过程分析测试系统 德国LaVision PIV/PLIF粒子成像测速场仪 PLIF平面激光诱导荧光火焰燃烧检测系统
