Abstract
The results of numerical modelling of combustion in a vortex chamber are presented. The calculations are performed using k-ε and k-ε with curvature correction of streamlines turbulence models. Upon combustion calculation of the well mixed mixture the Burning Velocity Model (BVM) was applied. The usage of the streamlines curvature correction allows to increase the accuracy of the prediction of the circumferential velocity component and the temperature field in the vortex chamber.
Highlights
Investigations of the oppositely directed swirling jets interaction confirm the presence of shear mixing layers that generate high-intensity turbulence, large-scale eddies and threedimensional vortex structures
The purpose of this paper is to investigate the usage possibility of the correction model for the streamlines curvature in calculation of highly swirling counter-directed flows, and to determinate the main modelling factors which influence the solution
For qualitative modelling of the temperature field in the vortex chamber, it is necessary to take into account the heat exchange with the walls, so further calculations are made with non-adiabatic walls
