Grid Generation for a Pump Collector.

Abstract

A simple scheme is presented which generates a surface-fitted grid for a pump collector with application to numerical solution of frozen vorticity flow inside the collector (the application to be covered in a later report). The scheme is two-dimensional in nature, but by a simplification of the collector geometry generates a three-dimensional grid. The procedure is very fast, requiring between two and three seconds of CPU time on an IBM 370/3033. Example grids are presented for several collector geometries. To develop a capability for computing such a grid would require considerable time and effort. The development time can be reduced drastically by making two simplifying assumptions about the collector geometry. Thus, a two-dimensional grid can be fitted to the cross sections of the simplified geometry and then rotated about the O axis to produce a three-dimensional grid. The originator-supplied keywords include: grid generation, computational fluid dynamics, pumps.
