Abstract

The paper deals with the modeling of vortex device with a minimum drag coefficient on a cold flow. The traditional method of intumescence of siliceous materials involves fast heating of raw particles in drum-type furnaces at temperatures of 800-1000 ºC. It is very energy-intensive compared to the method of intumescence in the vortex device at the temperature up to 300 ºC. The results of the calculation of aerodynamic drag of such cyclone are given in the paper. In order to determine the overall aerodynamic drag, pressure losses at all zones for the flow core are summarized, and wall, bottom and lid friction losses are taken into account. Mathematical modeling of 16 vortex devices which have different geometrical sizes was conducted. This allowed to find optimum ratios of the geometrical sizes of the device. The drag increases with the diameter of the inlet nozzles. The obtained calculation data coincide with of the calculation data of Ustimenko who investigated the change of distribution of velocities and pressure of vortex chambers taking into account a supply of thermal energy.

Dependencies of the coefficient of aerodynamic drag of the vortex device on geometrical and aerodynamic parameters are specified. The obtained results can be used for optimization of a design of the vortex device, including in the production dealing with the intumescence of porous disperse particles in the heated flow.
