| Abstract: | A calculation model of air bubbles motion in self priming centrifugal pumps with outer recirculation is presented in this paper . The different cases are respectively calculated and analyzed by using a numerical computation method. The computed results show that the initial diameter of air bubbles affects on its moving path, and the higher the rotation speed of impellers ,the faster the separated speed of air bubbles will be. |
