本文介绍激光空间流动显示技术及其在复杂流动中的应用。着重介绍了作者在激光诱导荧光流动显示(LIF)技术的研究和应用。较系统地讨论了若干原理和技术问题,并提供了一些实际应用的典型的流态照片。

Laser Spatial Flow Visualization and Its Application

The basic principle, advantages and main points of the techniques of the laser spatial flow visualization, specially Laser Induced Fluorescence (LIF),including the fluorescent dyes, the optical for-mming sets of the laser light sheet, so called'Boundary layer'and'shear layer'enjection methods, the record of the flow patterns and so on, are introduced systematically .Also the application of the laser spatial flow visualization and some results in the complex and turbulent flows, including the separated vortex flows, jet flows, turbulent boundary layer flows, are discussed and a number of the fine photos(original with colour)with various sectional views or spatial view on flow patterns and inner structures are provided.It is showed that the mentioned techniques could be and must be a very important and potential approach to investigate and analyse the flow patterns and structures for the deep understanding of the complex and turbulent flows.
