In this paper a mathematical model is developed and realized numerically for turbulent gas-dispersed nonisothermal swirling flows on the basis of Navier-Stokes type equations by using a modified k-{epsilon} turbulence model. Corrections taking account of the influence of particles and the flow swirling on k, {epsilon} are introduced into these latter. A finite-difference method of controlled volume is used to solve the equations. Computations are compared with experimental data on swirling single-phase flows in a cylindrical channel. Data are obtained about the influence of the nonisothermy on the length of the recirculation zone.
