SIMULATION OF HYDRODYNAMICS AND OF HEAT-MASS TRANSFER IN DISPERSED TURBULENT STREAMS

There the hydrodynamical and heat-mass transfer processes in two-phase turbulent streams with the impurities of particles or drops have been studied. The description manner of dispersed turbulent streams, which is new in essence, has been developed on basis of use of equation for the function of distribution probability density of characteristics of dispersed phase. The new results about the formation mechanisms of averaged and pulsation characteristics of dispersed impurity, about the inverse influence of particles on the flow characteristics of carrier phase have been obtained. The new computation procedure of rate of deposition of particle impurity in the tubes has been created. The new results about the collision process of particles in the non-uniform turbulent stream have been obtained. The gasification simulator of cokes of high-ash coals has been constructed. The new physicochemical simulator of break-down of organic heat carriers under the conditions of liquid-phase oxidation has been developed. The physicochemical simulator of processes in the absorption zone of sulphur-purifying plant to catch the sulphur dioxide from the smoke gases of high-capacity steam electric stations has been createdAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
