CFD simulation and experimental validatation of Jet Mixer with Conical bottom

摘要

Many experimental studies have been carried out to study the mixing in liquid jet agitated tanks. In this study numerical simulation is carried out to study the effect of shape of tank on mixing time in a conical based cylindrical vessel. This paper reports the results of the study on the flow generated in such tank. For this purpose, a tank is modeled using FLUENT 6.1. The model has the ability of simultaneous solving of continuity, the Reynolds-averaged Navier -Stokes (RANS) equations and employing various types of turbulence models. The results show that there are considerable differences between the various geometries taken. The geometry considered is a Cylindrical tank with a conical bottom. A bottom pump around tank with a single jet arrangement is used. An experiment is also done to validate the results obtained by the numerical study
