Аннотация: The effect of two-parameter k-e and k-? SST turbulence models and Reynolds stress model RSM on the description of processes at pulverized coal combustion in a furnace with a swirl burner is calculated in the present work. The mathematical model, which included the description of carrier phase motion based on the RANS approach, calcПоказать полностьюulation of radiation transport through the P1 method, motion of particles based on the Lagrangian approach, combustion in the gas phase based on the hybrid model, and coal particle burning in the diffusion-kinetic approximation, was chosen for calculations. The calculated data were compared with experimental results on combustion of pulverized coal flame in the presence of flow swirl at the fire test bench with capacity of 2.4 MW. Comparative analysis showed that k-epsilon and k-omega SST turbulence models and Reynolds stress model have a little effect on distribution of axial and tangential velocities, temperature, and concentration of gases in the furnace.
