Abstract

In Eulerian variables theoretical model for calculation of hydrodynamic and heat transfer in gas solid two-phase flow in a round pipe and jet is submitted. The model is based on united system of equations describing turbulent characteristics of particles in non-isothermal flow, and the boundary conditions representing interaction of particles with a rough pipe surface. Influence of gradients of turbulent velocity and temperature fluctuations, and ratio between thermo physical properties of particles materials and carrying gas on motion and heat transfer in the dispersed phase is investigated. Calculation results are compared with experimental data.
