Abstract
Present paper deals with the results of the experimental investigation regarding the velocity distribution inside the vortex chamber-type sediment extractor at high water abstraction ratio. Data are collected in the laboratory on a vortex chamber. A programmable electromagnetic shunt (P.E.M.S.) flow meter is used to measure the velocity components along tangential and radial directions at well-defined nodal points inside the chamber. Graphs for tangential and radial velocity distributions are plotted at various depths along radius of the chamber for highest water abstraction ratio (17%). It is found that velocity distribution throughout the chamber is not uniform due to unsymmetrical positions of inlet, outlet channels, and under flow outlet. In some part of the chamber, it follows the law of Rankine vortex-type velocity distribution.
