摘要：

Gas and vapour single phase ejectors are commonly applied in variety of thermal systems for power generation as well as refrigeration. The general difficulties in design of the ejector system are lack of the reliable models of the ejectors. The most useful tool for prediction of operation of the ejector is CFD which requires selection of the turbulence model. The paper presents the flow visualisation investigations with application of PIV technique along with CFD modelling results based on which recommendation of the k-epsilon standard turbulence model is formulated.
