| Abstract A solution method is developed to obtain three-dimensional velocity and pressure distribution within a centrifugal pump impeller. The method is based on solving fully elliptic partial differential equations for the conservation of mass and momentum by finite difference method to convert them into algebraic equations. The effect of turbulence introduced using a certain algebraic model based on modified Prandtl’s mixing length theorem. The conical coordinate system is used in order to fit an arbitrary hub-to-shroud shape. The set of algebraic equations is solved simultaneously by “SIMPLE” algorithm to obtain velocity and pressure distribution within the impeller passage. The results are compared with previous experimental results of other researcher under the same operating circumstances and acceptable agreement has been found.
