Numerical and experimental analysis of two phase flow in ejector

When the ejector was applied in the natural gas exploitation and sea water desalination industries, the ejector always operated on the two phase operation, because of the primary fluid or the induced fluid usually companying some water inside. The water inside the primary and induced gas will affect the ejector performance. In the present study, the experimental and CFD methods were used to investigate the two phase flow inside the ejector, when the water was injected into the induced flow. The results show that: when the water was injected into the induced flow, the experimental results decreased, as well as numerical results. The numerical results agreed with the experimental data, with the maximum deviations less than 20% for critical mode and less than 40% for sub-critical mode.
