دانلود کتاب Hydrodynamics and mass transfer in downflow slurry bubble columns

"Slurry bubble column reactors are intensively used as a multiphase reactor in the chemical, biochemical, and petrochemical industries for carrying out reactions and mass transfer operations in which a gas, made up of one or several reactive components, comes into contact or reacts with a liquid. This new volume, Hydrodynamics and Mass Transfer in Downflow Slurry Bubble Columns, describes the hydrodynamics of three-phase gas-liquid-solid flow in a downflow slurry bubble column. The efficiency of the downflow gas interacting system is characterized by the self-entrainment of secondary gas. The book covers the gas entrainment phenomena, gas holdup characteristics, pressure drop, gas-liquid mixing characteristics, bubble size distribution, interfacial phenomena, and the mass transfer phenomena in the downflow slurry system. Gas holdup has been analyzed by different models. A model for pressure drop in the system based on mechanical energy balance within the framework of dynamic interaction of the phases has been formulated and described. The model includes the effect of bubble formation and form drag at interface on the pressure drop. Interpretation of mixing behavior has been done by velocity distribution model"--  Read more...
