摘要：From the ample computational results, the relationships among maximum entrainment ratio, expansion ratio and critical compression ratio were concluded. A power correlation between expansion ratio and Mach number at the nozzle outlet was found. Using two dimensionless parameters, namely expansion ratio and critical compression ratio to replace actual motive fluid pressure-suction pressure and critical discharging pressure to analyze the effect of the operation parameters on the ejector performance, can make the results more universal and useful in ejector designing and ejector efficiency.
