Abstract
This paper describes the flow visualization of particles in a cylindrical vessel for dry using PIV. The working fluid is air. The particles of foaming styrene and plastic beads were applied as tracers. Experiments were carried out for various Reynolds number and three positions of a nozzle. Results show that flow is composed of the impingement on the side wall, small recirculating flow and swirl-rising flow. Effects of the nozzle positions affect the impingement position on the wall.
