Pavlenko I. Scientific and theoretical foundations of vibrational processes in heterogeneous systems

The dissertation is devoted to the solution of an urgent scientific and technical problem of processes intensification in separators, classifiers, and prillers by developing the scientific and theoretical foundations of the process of vibrational impact on heterogeneous systems, modeling the hydrodynamics of modular separation devices, analysis of the influence of joint convective heat transfer processes and non-stationary capillary fluid motion during filtration on the efficiency of separation for gas-condensate systems, as well as prevention of harmful effects of secondary processes and the influence of vibrations on the formation of monodisperse granules. For the first time, an increase in separation efficiency due to vibrational and filtering principles of separation has been theoretically justified. Scientific and theoretical foundations of hydroaeroelastic interaction of separation elements with the gas-liquid flow have been developed. The existence of a critical Weber number in the process of secondary crushing of a dropping liquid has been theoretically substantiated. The scientific and theoretical fundamentals of the liquid film downflow have been developed with combined convective heat transfer on the cooled surfaces of contact elements. The scientific foundations of the theory of ceil structures have been created for the study of separation and filtration processes. A formula for determining the specific interfacial surface in the processes of chemical technology has been clarified, and the mathematical model of the process of energy transfer from a vibrational actuator to a fluid melt in a vibrational priller has been refined.
