Abstract Two jet pumps with superlarge arearatios (574 and 6005), respectively, were designed according to the conventional theory and the engineering requirements. Based on the finite volume method, the Realizable k-ε turbulence model with the standard wall function was adopted in the three dimensional flow simulations and structure optimization of the pumps. The simulation results indicated that the best efficiency point moves to a higher flow ratio and the optimum throat length increases with area ratio. Six jet pumps were manufactured according to the optimized parameters; subsequently their performance was tested under different driving pressures. There were six area ratios through the combinations of two size nozzles and three throat diameters. The experimental data show that the fluid flow inside those pumps has selfsimilarity like a conventional jet pump. The existing theory for predicting cavitation flow ratio overestimates the cavitation performance of those pumps, and it needs to be updated. The experimental data agreed well with the simulation results, confirming the reliability of numerical simulation and the feasibility of structure optimization. The investigation into the pumps with super area ratios has extended the application range of jet pumps.
