Paper Abstract

In this paper, a combined measurement technique of Particle Image Velocimetry (PIV) and shadowgraph is proposed to investigate the environmental fluid dynamics. This measurement system is based on a PIV system, with a backlight added to produce the shadow of dyed water. The images recorded by a CCD camera are then processed for the PIV and shadowgraph data, separately. The experimental results show that this technique is well suitable for the investigation of time-dependent flow field with temperature variation. Fairly good agreements with the experimental and CFD results are achieved.
