Flow field of centrifugal pump (Pump flow passage includes suction pipe, impeller and volute casing.) obtained by solving the Reynolds average Navier-Stokes equation. Computational performance curve is compared with measuring curve. The result demonstrates that the computational head versus discharge curve is coincident with the measuring curve; the computational efficiency curve is coincident with the measuring curve in large-capacity area, in lower-capacity area not so well. Though the simulation result is not accurate highly in part operating domains, the pressure and velocity distribution and other flow characteristics in whole flow path in all operating domain produced by the simulation are also useful to analyze flow problems in dredge centrifugal pump.
