Sidorenko S. Hydrodynamics and mass transfer in dispersive contact device of mass transfer centrifugal apparatus

In dissertation performed theoretical and experimental study of hydrodynamic and mass transfer characteristics of mass transfer centrifugal apparatus with the proposed type of resistance device. Contact device is assembled with axisymmetrical ring contact elements made of metal mesh. Elements are spaced from one another. The physical and mathematical model of the hydrodynamics of the phases in the contact device are elaborated, the dependences for calculating the rate of gas flow resistance and dispersion characteristics of the liquid are elaborated. Experimental influence of regimen (rotor speed, velocity, gas density and irrigation) and design (a step between the contact elements) parameters of hydrodynamic resistance on device performance and mass transfer kinetics in the machine. As a result of experimental data processing coefficients for theoretical models of hydrodynamics of liquid and gas and mass transfer results are summarized in the form of criterial equations. As a result of theoretical modeling and experimental research methodology of engineering calculations centrifugal apparatus of the investigated type of resistance device. Based on calculations by a method developed and investigated working conditions in the rectification unit on the basis of two mass transfer centrifugal machines.
