Abstract The self-priming process of a pump involves a complex gas-liquid two-phase flow. Studying the distribution of gas and water and the evolution of their flow in the pump is of great importance to optimize this process and shorten the pump self-priming time. In the present study, a standard k-ε turbulence model and a multiphase flow model have been used to simulate the self-priming pump process considering four different reflux hole areas. A comparison of the distribution of air and water distribution on the axial surface and inside the volume have been carried out for the different considered cases. The pattern… More >
