Computer-aided analysis of three dimensional confined vortex flow
Abstract
The swirling, incompressible flow within a short vortex chamber with a central exhaust has been studied analytically. A set of non-dimensional differential equations are developed for the inner core regions where the flow field is highly complex. The non-linear differential equations are solved numerically using the Runge-Kutta method. All the fluid parameters including the apparent viscosity match at the boundary between the annular region and the inner flow region of the vortex chamber. Flow characteristics and velocity profiles for the whole chamber were analytically obtained. The analytical results also provide a good indication of the variation of apparent viscosity across the inner core region.
