Laminar Three Dimensional Boundary Layers with Swirl in Slip Flow Regime

Abstract

The effect of slip on swirling, low speed flows of slightly rarefied gases in the slip flow regime in a three dimensional axisymmetric laminar boundary layer is investigated by similarity solution approach and by use of perturbation techniques. The governing ordinary differential equations are solved numerically using Runge-Kutta-Gill method. The results show that the skin friction and the heat transfer are reduced due to the effect of slip.
