Abstract
This research presents investigations on the discharge coefficient of a circular orifice located at the apex of an inverted conical hopper attached to the bottom of a cylindrical vortex chamber. A circular jet inflow tangentially enters the vortex chamber at the top periphery of the conical hopper. Different sizes of orifices and inflow jet discharges were applied in the experiments to investigate the variation of the discharge coefficient. The effect of overflow at the upper outlet on the discharge coefficient was also investigated. Based on the test data, empirical relations for the discharge coefficient are proposed. It is found that in the presence of tangential jet inflow, the discharge coefficient is considerably smaller than that without tangential jet inflow and the presence of overflow significantly reduces it.
