Abstract: Vorticity is a basic parameter of the fluid flow. Vortices occur as basic phenomena and are looked as the basic structure of turbulence. This paper proposed a new numerical method, called as the method of vorticity tuning, on the basis of J . C. Wu's research. The velocity and vorticity fields in a tangentially fired furnace were computed by the new method. The computed velocity field was basically consistent with the experiment. In comparison with the SIMPLE algorithm, the n ew method is superior under the same condition of the net.
Keywords: tengentially fired furnace, numerical simulation, vorticity tuning method.
