Aerospace Instrument-Making Annotation << Back Aerodynamics of the swirling flow in vortical torches Sh.A. Piralishvili, A.I. Gur’yanov, Akhmed Mamo Demena, S.M. Khasanov Research results of the thermogasdynamics of the three-dimensional swirling flow of viscous gas in vortical torches are submitted. Precession characteristics of the vortical flow core in the cylindrical chamber depending on regime parameters of the torch are received. The estimation of influence of the secondary vortical structures formed in twirled current, on hydraulics of the torch and kinematics of the flow is executed. Conditions of the organization of aerodynamic stabilization of the flame in the turbulent flow with spin and connected with it the secondary gas-dynamic phenomena are shown.
