Entrainment ratio analysis of compress/ejector refrigeration system

Entrainment ratio is one of the main characteristic parameters of ejector. Studding on it is of a quiet importance to the compression/ejector refrigeration system. Computational Fluid Dynamics (CFD) is used to simulate the inner flow and analyse the influence of driving fluid pressure and outlet pressure to the performance of ejector. By simulating the relations between driving fluid pressure, working fluid pressure, outlet fluid pressure and entrainment ratio are obtained. The conclusion provides valuable guiding significance for the working conditions setting.
