• Abstract

In this paper, study on the performance analysis of jet ejector has been carried out using a constant rate of momentum change diffuser. The various losses that occur in different regions of jet ejector have been quantified and an attempt has been made to increase the efficiency of jet ejector by reducing the losses based on minimization of entropy method. In the present work, new technique has been implemented to minimize the momentum difference between the motive and the propelled streams. This was carried out by changing the design of the throat and diffuser profile. The geometrical design parameters were obtained by solving the set of governing equations, a CFD package; FLUENT and it has been effectively used to evaluate the optimum entrainment ratio for a given set of operating conditions.

Keywords: Jet pump, Entrainment ratio, Irreversibility, CRMC.
