摘要
化工研究中经常要涉及到流体,需要对流体的流速进行测量。激光多普勒测速仪作为一种非接触式测量手段,具有精度高、重复性好、动态响应快、测量范围宽等优点,因而在流场、湍流、传质、传热、流型、燃烧等方面获得了越来越广泛的应用。本文综述了激光多普勒测速仪在化工研究领域作为一种新测量手段获得的应用。
The research work in chemical engineering always deals with fluid, its velocity needs to measure. The laser Doppler velocimeter (LDV) used as a non contact measurement means features high accuracy, good repetition, rapid kinetic responsibility and broad interval of measurement and so on. Hence the LDV is widely used in chemical engineering research, especially in the fluid flow measurements, turbulence, heat and mass transfer, flow structure as well as combustion. The potential use of this advanced measuring technique in chemical engineering research is reviewed.
