DUAL STREAM FUNCTIONS FOR 3D SWIRLING FLOWS

摘要

Sets of dual stream functions that can be used to describe three dimensional vector fields, typical of those in swirling flows, are described. The particular interest is those situations where one of the stream functions is multivalued. The ways that they can be used to represent well known idealised flows is presented with the purpose of demonstrating their potential for application to the visualisation of three dimensional flows.
