2nd Edition . - Kazan: Fatherland, 2009. - 224 s. The monograph considers the main patterns and methods of modeling of hydrodynamic and mass-exchange processes in two-phase turbulent gas-dispersed flows taking into account random factors. methods of intensification and increase of efficiency of processes and devices for purification of industrial gas emissions from gaseous and highly dispersed impurities in devices with intensive hydrodynamic modes . Probabilistic-stochastic approach and methodology for modeling gas-dispersed flows are proposed, taking into account the deterministic-stochastic nature of the turbulent motion of continuous and dispersed phases using the methods of probability theory and the theory of random processes. Probabilistic-stochastic models of gas-dispersed, dispersed-ring and twisted two-phase flows were developed, the method of calculating the particle concentration profile and its changes along the length and radius of the channel. The monograph is intended for specialists , Research Fellows and Postgraduates , Hydrodynamic modeling, heat and mass transfer processes in turbulent two-phase streams , Development and design of gas treatment equipment , can be useful for students of technical and technological specialties of higher educational institutions.
