Comparison of numerical and experimental investigations of jet ejector with blower

In this article, extensive numerical study of performance improvement of jet ejector is presented. The effect of independent variables (primary nozzle - pressure, temperature, mass flow rate, secondary nozzle - velocity, and diffuser pressure) on entrainment ratio of jet ejector were numerically predicted by using an Asymptotic Computational Fluid Dynamics (ACFD) technique. The variations of independent variables on entrainment ratio were drawn for a range of parameters. Based on the ACFD technique, separate correlations were developed for the system with and without blower. The parity plots were drawn between numerical and correlated data. It is also found that the maximum deviation of 6% and 8% were obtained for the system with and without blower. The obtained numerical results of system with blower are compared with the experimental analysis of the jet ejector system with blower. It is also found that the numerical and experimental results are comparable with very good agreement.
