Sediment-Laden Negative Buoyant Forced Plume in Uniform Flow

Abstract

The paper presents the behavor of sedimentladen negative buoyant plume issued vertically into uniform flow. Special attention is paid on the effect of settling particles on plume motion. Experimental and theoretical studies were made on the variations of plume properties, such as plume trajectories, grouth of width and decay of concentration and velocity. The path of maximum velocity was pulled down due to settling of sediments and there found a vertical gap between the path of maximum cocentration and maximum velocity. Except these features, the plume motion was almost the same as that of non-settling matter.
