| Abstract: | The geometrical parameters of the ejector significantly affect its performance in boosting the flow from low-pressure gas wells. Several studies have identified that primary nozzle exit position (NXP), primary nozzle exit diameter (Dp), and mixing tube diameter (Dmt) are among the most influential factors. In this study, computational fluid dynamics (CFD) simulation is used to investigate the effects of these parameters on the entrainment ratio and isentropic efficiency of the ejector, particularly by analyzing the velocity and pressure fields within the ejector. After model construction and validation against published data, we found that the optimal ejector geometry is NXP/Dt = 6.346, Dmt/Dt = 2.615, and Dp/Dt = 1.275. The maximum entrainment ratio and corresponding ejector efficiency at the optimum geometry are 76.3% and 29.6%, respectively. The optimum geometry is obtained when the double-choking flow forms within the mixing chamber, as indicated by the velocity and pressure profiles. These findings align with our previous study, further emphasizing the impact of flow profiles on ejector performance. Furthermore, a general cubic regression equation is developed for ejector optimization by combining geometrical and operational parameters. [ABSTRACT FROM AUTHOR] |
