Abstract

Analysis of flow in a vortex chamber has not been fully studied, because it has mainly two complex flow patterns; one is curved wall jet, the other is vortex breakdown. Using water as the operating fluid, the experiments were performed with vortex diode and curved wall. Measurements were performed about the distribution of static pressure by a Hg-manometer, and about those of tangential and radial velocities by a laser doppler velocimeter. The following facts are especially pointed out; 1) Tangential velocity distribution shows apparently an existence of a curved wall jet in outer area and a free vortex in inner area of the vortex chamber. 2) Flow in the chamber from inlet to outlet is combined with a free vortex and a curved wall jet. 3) Growth of the length scale for curved wall jet is directly proportional to distance from a nozzle.
