Aerodynamic structure of a swirling turbulent flow in a vortex furnace

Abstract

Abstract Insufficient study of the swirling flow structure, stability of high-temperature circulating zones, intensity of fuel and oxidizer mixture formation and other determining phenomena in the vortex furnaces indicates insufficiency of scientific substantiation of the methods for their calculation. Therefore, further detailed studies of aerodynamics of a turbulent swirling flow in a vortex chamber with intersection of the main flow by the inlet tangential jets aimed at the development of promising combustion devices seem to be relevant. The results of numerical simulation of the turbulent swirling flow aerodynamics with preference given to the modern models of turbulence and numerical schemes of high-order approximation are presented.
