In order to study the performance and characteristics of the internal flow field of gas-liquid jet pumps with air as working fluid, the gas-liquid jet pump test models with different structures were designed. Boundary conditions were determined according to the data obtained from test. The gas-liquid jet pump was numerically simulated in the same working-gas pressure and different parameters by k-Ε turbulence model and VOF method. The simulation results show that the gas-liquid jet pumps with expansion nozzles has good velocity and static pressure distributions, the air-liquid jet pumps with 5 mm distance from throat to mouth and that with 6 mm diameter of mixed chamber have good velocity distributions. The gas-liquid jet pumps, nozzle with the expansion, mixed chamber with 5 mm from throat to mouth and 6 mm diameter have better velocity distributions.
