Abstract
In this paper, the author tried to find out how clearance between impeller and tongue would affect the pressure fluctuation. By changing the diameter of the impeller, six transient simulations of a centrifugal pump were conducted. Data from different monitoring points were recorded and analyzed. The result shows that pressure fluctuation decreases with the increasing of the clearance. But the high-frequency noise does not change with the clearance.
