In order to understand the flow patterns through a semi-open impeller of centrifugal pump for solid-liquid two-phase flow,the three-dimensional turbulent flow through the impeller is investigated by numerical flow analysis.The SIMPLEC algoirthm with body-fitted corrdination and staggering grid systerm is used for the solution procedure of the discretized equations based on the navier-Stokes equations and the standard k-#omega# model.The calculated result for pressure distribution is compared with experimental data which is measured on the spring casing in suction side.And the good agreement is shown between the calculated result and experimental one.
