U.S.-China Cooperative Research (Eng.): Motion of Gas-SolidSuspension in a Cyclone

该奖项由美国伊利诺伊大学厄巴纳分校的邵立苏教授和中国北京清华大学的周立兴教授合作研究，支持对旋风中气固悬浮运动的研究。研究将解决旋风分离器的收集效率与流体和颗粒在其中的运动之间的关系。由于缺乏对这些运动细节的了解，现有的关于旋风分离器的知识是有限的，这些运动的细节只能通过精确的激光多普勒测速仪来测量。精确的测量将使验证先进的分析研究和计算机建模成为可能。本研究的重点是帮助产生用于处理和控制颗粒排放的旋风收集器的最佳设计标准。该项目的合作性质涉及使用中国顶尖工程大学清华大学的专业激光设备，并补充了苏博士正在进行的多相流研究。

This award for cooperative research between Shao L. Soo of the University of Illinois, Urbana and Professor Zhou Lixing of Tsinghua University, Beijing, China, supports research on the motion of gas-solid suspension in a cyclone. Research will address the relations between the collection efficiency of a cyclone separator and the motions of fluid and particles in it. Existing knowledge on cyclone separators is limited by the lack of knowledge of the details of these motions which can only be obtained by measurements with an accurate laser-doppler velocimeter. Accurate measurements will make possible validation of advanced analytical studies and computer modeling. The emphasis of this research is to help generate optimum design criteria for cyclone collector's used in processing and control of particulate emissions. The cooperative nature of this project involves use of specialized laser facilities at Tsinghua University, a top engineering university in China, and complements Dr. Soo's ongoing research on multiphase flow.
