Abstract

The purpose of this paper is to evaluate the performance of the ejector using two different streams of fluids. To investigate the ejector performance, different operating conditions were applied to ejector. The value of motive and suction pressure were considered to be constant while discharge pressure of ejector was changed continuously. Motive flow was considered to be saturated steam while Suction flow is composed of air and steam. In this mixture, the mass fraction of air and steam changed in the range of 0–1. Ejector performance curves are extracted for different mass fractions of air and steam. The resulted performance curves indicate that the variation of mass fraction of species that were present in the suction flow mixture had significant effect on the performance of ejector. Results showed that as the mass fraction of air in suction flow was increased, the ejector entertainment ratio was increased as well. Also can observed that the variation of mass fraction of suction flow don’t have significant effect on break point of ejector performance curves.
