Abstract

The purpose of this paper is to study the influence of geometry parameter on the ejector performance. The CFD results were verified with available experimental data. Flow field analysis was also carried out in this study. Variation on the geometry parameter was made by varying the angle of converging duct those are $0.5^{\circ}$, $2.0^{\circ}$ and $3.5^{\circ}$. The converging duct with an angle of $0.5^{\circ}$ gives the highest value of entrainment ratio that is 0.941. Furthermore, from this study it can be concluded that the entrainment ratio decreases with respect to the increase of angle of convergence duct.
