Abstract

The paper presents a  numerical solution of full Navier-Stokes equations for an intensively swirling flow in  an axisymmetric channel disc-loaded in the input cross-section and supplied with a throttle of the peripheral slot type at the opposite end of the channel with a central hole for feeding additional masses of gas. The flow patterns, thermodynamic parameter distribution fields are obtained. The results of numerical computation are compared to the experimental data for vortex tubes with an additional stream. Formation of large-scale vortex structures is noted. The results of numerical calculation and computer visualization can be used to further refine the physical model and methodology for calculating characteristics of vortex tubes.
