Development of a Navier-Stokes Analysis for the Flow in Disk Pumps.

Abstract

A technique has been developed to solve the Navier-Stokes equations for the flow in disk pumps. The technique uses a linearized block implicit-alternating direction technique to efficiently solve the unsteady governing equations to a steady state with appropriate boundary conditions and initial conditions. The resulting code was used to calculate the flow in two different geometries under the same flow conditions. Demonstration calculation indicates that the code will be a valuable tool in analytically evaluating the performance of existing and future disk pumps. Keywords: Computational fluid mechanics; Alternating direction implicit.
