The hydrodynamics and heat and mass transfer of particles under conditions of turbulent flow of gas suspension in a pipe and in an axisymmetric jet

A mathematical model for the calculation of the hydrodynamic and thermal parameters of dispersed impurity in a round pipe and in a jet is given in Eulerian variables. The model is based on a unified set of equations describing the turbulent characteristics of particles in nonisothermal flow and of boundary conditions representing the interaction of the particles with the rough channel surface and the boundary of submerged jet. The effect of the anisotropy of turbulent fluctuations of the particle velocity and of the correlation between the thermal properties of the particle material and carrier gas on the intensity of momentum. heat, and mass transfer in the dispersed phase is investigated. The calculation results are compared with the experimental data.
