The two -dimensional mathematical model of strongly swirling gas - partical turbulent flow and pulverized coal combustion developed and formulated in paper (Ⅰ) was applied to the systematic numerical simulations of isothermal gas flow

gaseous combustion

and pulverized coal combustion in the novel coalfired vortex combustor. General agreement was achieved between the calculated results and the cold flow and combustion test data. The simulation results delineate the detailed properties and characteristics of flow

heat transfer

and combustion in the vortex combustor.
