Abstracts:

Processes in which processing is carried out in heterogeneous media with film-like modes of their implementation are often in many industries, such as food processing, petrochemical, energy, medical, while they are studied insufficiently. The aim of this work is the mathematical simulation of two-phase highly viscous emulsion separation process during film-like flow along heated complex-shaped working surfaces based on the equations of mechanics of multiphase with account of heat and mass transfer with environment. The developed mathematical model consists of the nonlinear equations of conservation of mass, momentum and energy, written and simplified for an arbitrary orthogonal coordinate system associated with the surface of a process implementation with account of its features and relevant boundary conditions. The continuity equations and momentum equations are solved analytically, and approximate Slezkin method is used to solve the energy equations. Numerical calculations based on the developed mathematical models were performed for the example of the two-phase emulsion - heavy pyrolysis resin, and obtained results for different values of the process mode parameters are in good agreement with the experimental data obtained at the laboratory unit. The obtained results are new and in special cases coincide with the known from the literature sources related to solving similar problems. They are of practical interest for modeling various processes related to the phase separation of the highly viscous two-phase media, implemented on heated surfaces in film-like flow regime.
