The Influences of Impeller Eccentricity on Front Leakage Flow

Abstract:

A numerical analysis on the steady-state front leakage flow of an eccentric impeller is done based on a bulk-flow model. A set of nonlinear partial differential governing equations is derived on a control volume from the flow. The SIMPLE algorithm is used to develop the computational procedure for solving the equations. A MATLAB computer program in accordance with the computational procedure is written to conduct the numerical calculations. Numerical results are represented with the diagrams of pressure and velocity distribution of the flow. The influences of the impeller eccentricity on the flow are examined in a limited range of engineering practice. Conclusions are reached that the impeller eccentricity has substantial effects on the pressure and velocity distributions of the front leakage flow.
