Prof. Dr.-Ing. Sergiy Antonyuk

Many industrial processes are realized by two- or three-phase flows. They consist of a continuous phase (ambient medium) and a disperse phase (solid particles, droplets and gas bubbles). The interactions between the phases play a decisive role in the heat and mass transfer, separation or mixing of the phases, growth or breakage processes and are therefore crucial to the success of the process.

In this course, the physical principles of multiphase flows in gas/liquid are explained and the technical processes and some apparatus with multiphase processes are presented and designed. An important focus of this course will be on calculation methods, modeling and simulations with modern numerical tools. Corresponding exercises are carried out on the high-performance computer of the RHRK.
