Abstract :
In this paper, Fluent 6.2 is employed to investigate the flow structure of the steam ejector used in the steam jet refrigeration system. Effect of the operating pressure on the entrainment ratio of the ejector is discussed. For a given ejector, there exists an optimum primary fluid pressure at which maximum entrainment ratio is obtained. Entrainment ratio is increased by increasing the secondary fluid pressure and decreasing the discharge pressure.
