Abstract The aim of this research is to study a flow in an ejector equipped with variable throat area of the primary nozzle. Using a CFD technique, flow phenomena, mixing structure and performance of the ejectorwere analyzed and explained. In this study, a 2D-axisymetric model was used. Realizable k-epsilon model was applied for a turbulence model. R141b was selected as a refrigerant fluid. Instead of changing the size of the throat diameter, variation of throat area of the primary nozzle was achieved by changing a wedge
