The aim of this study was to reveal the dynamic characteristics of the liquid-liquid ejector with a pulse current. A three-dimensional ejector model was established. The performances of sucking fluids and mixing performance between the steady ejector and pulsed ejectors with different frequency and amplitude were analyzed. The simulation results showed that the efficiency of the pulsed ejector was higher than that of the steady ejector under the same operating conditions. The ER (entrainment
