Physical modeling of the structure of turbulent swirling flow is carried out in the isothermal laboratory model of the vortex furnace new design with distributed tangential inlet of air jets. The presence of burner jets (in the studied design of vortex furnace), distributed along the perimeter and oriented in the opposite directions, provides the flexibility to control flow structure and regime parameters. The horizontal axis of flow rotation increases the completeness of burnup of the fuel. There is investigated the method of control of the flow aerodynamics in the vortex furnace due to the use of a cylindrical insert, mounted on the axis of the combustion chamber. Flow velocity measurements have been performed using the method of laser Doppler anemometry. The distribution of the average flow velocity in the volume of furnace is obtained. It is shown that the presence of cylindrical insert makes it possible to eliminate the precession of vortex core. The obtained results can be used for the solution of the problem of determining the optimum diameter of insert on the basis of numerical simulation of furnace processes.
