Present work is directed to further perfection of a modeling of the structure and heat transfer processes in gas-droplets near-wall screens in a tube. The problem statement in the present work is based on the Eulerian-Eulerian two-fluid model for transport processes in the gas and dispersed phases in the turbulent gas-droplets jet. We used the model [High Temp. 40(1) 2002 78] for computation of averaged motion, heat transfer and squared velocity fluctuations of dispersed phase. The gas phase turbulence was modeled with the LRN k-ε [AIAA J. 36(1) 1998 38] model with taking into account the effect of evaporating droplets on the kinetic turbulence energy and the rate of its dissipation. The present paper takes into account the influence of droplets deposition and vaporization of deposited particles on the tube wall and particles evaporation in the near-wall jet. Developed numerical model was tested by comparison with experimental and numerical data for gas-droplets non-isothermal flow in a tube and in a near-wall screen.
