摘要
在流场速度场测量中 ,示踪粒子是显示流场运动的媒介和工具 ,示综粒子对流场的跟随性直接影响着流场速度场测量的精度。本文从 Bassat- Boussinesq- Oseen( BBO) [1 ]方程出发给出了粒子跟随性函数和粒子在匀角速旋转流体中的运动公式 。
In flow velocity field measurement, the tracer is the medium and tool to display flow movement The tracer's characteristic of following flow directly influences the accuracy of measurement From Bassat Boussinesq Oseen(BBO) [1] equation, the paper presents the function of tracer's following characteristic and movement formula of tracer in even angle rate flow, and discusses the parameters which effects tracer's following characteristic
