This paper summarizes the numerical analysis of a liquid-liquid ejector pump with focus on the accuracy of the employed cavitation model and in view of its potential application as a dualor multi-liquid mixing and injection system. While the use of gas-phase or gas/liquid-phase ejection systems has found wide application in gas/hybrid burners and scrubbers for air pollution control; the use of ...

Objective . With the decreasing use of refrigerants with a high global warming potential, increasing efficiency refrigeration machines using natural working fluids is very urgent task. The CO2 booster refrigerant cycle may be optimal for fields commercial refrigeration, climate engineering and heat pumps, but needs to adapted regions hot climates. purpose study also systematize possible ways im...

This study aims experimentally to investigate the performance parameters of R134a and alternative R516A refrigerant in two evaporator ejector cooling system (DEES) at different air velocities evaporator#1. Firstly, tests were carried out with under steady-state conditions then repeated low GWP refrigerant. As R134a, higher capacity was achieved velocity values. When value 1.1, 1.7, 2.2, 2.7 m s...
