Transfer processes in turbulent gaseous suspensions

Subject of inquiry: turbulent weakly dust-laden flows with inactive and reactive particles of solid and liquid phases. The aim of the work is to investigate small-dispersed particles influence on turbulente characteristics of carrier gas using spectral theory of turbulence. The results of the investigation have been used when desining concrete turbulent flows. A method has been developed for solving a dynamic equation designed for spatial spectrum of turbulent fluctuation velocity. Small particles influence on turbulent characteristics of carrier phase has been determined, as well as the dependence of relative turbulent diffusion coefficient upon particles concentration. The work covers the usage of heat transfer in combustion chambers and shaft furnaces when modelling with the obtaining of more accurate distributions in velocities, temperatures and components concentrations. The developed procedure allows to design optimal operating and structural parameters of such aggregates. The results of the investigations have been used when reconstructing aggregates at Ust-Kamenogorsk Lead-Zinc Integrated WorksAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
