Abstract

Abstract

There are usually three dimensional structure in the complex flow flelds involving shock waves and interaction between shock waves and boundary layers. It is of low spatial resolution to study these flow flelds using traditional ow visualization techniques, such as schlieren, shadow and interference methods, and the three dimensional characters are usually hard to be identi ed. The Nano-tracer based Planar Laser Scattering (NPLS) technique is a new method developed recently for the measurement and visualization of supersonic three dimensional complex flow flelds. It has achieved spatiotemporal resolution, and is thus a good method for the measurement of complex flow flelds involving shock waves. In recent years, mainly with NPLS technique, we have carried out vast experimental research on typical complex flows in the area of aeronautics and aerospace, including supersonic flows over bullets, supersonic mixing layers, supersonic boundary layers and the interaction between shock waves and boundary layers. And advantages of the NPLS technique are clearly revealed in these studies. Process is elucidated in this paper for the application of NPLS technique to the measurement of complex flow flelds involving shock waves.
