Abstract
Present paper deals with the experimental investigation of flow mechanism such as velocity and water surface profile inside the vortex chambers. Extensive data have been collected in the laboratory on two types of vortex chambers, one being simple model chamber and other was a pilot model of the vortex chamber. In model vortex chamber, only the tangential velocity and water surface were measured with pitot tube and vertical pressure gauge meter respectively while in pilot model of the chamber, theses parameters were measured using Programmable Electro Magnetic Shunt flow meter and vertical pressure gauge meter respectively. It is found that in both type of the chambers, the tangential velocity conforms the free and forced vortex laws i.e. for forced vortex and for free vortex . Water surface profiles for free and forced vortex motions are the hyperboloid and paraboloid of revolution, respectively.
