Numerical simulation of fluid particle interaction with a vortex structure

Fluid particles (bubbles/droplets) dispersed in a liquid are part of multiphase systems that occur in many industrial processes (aeration, emulsification, extraction, etc.). Understanding the mechanism of interaction of these particles with the vortex structures occurring in the liquid is essential for modeling and numerical simulation of multiphase systems. The doctoral project is focused on numerical simulations of the interaction of a fluid particle (bubble or drop) with a defined vortex. The goal of the work will be to develop models that will be able to predict the outcome of the interaction, i.e., deformation of the original particle, or its breakup into several smaller particles, deformation of the original vortex, change of its energy, or its disintegration.

The workplace at ÚCHP has ANSYS Fluent and COMSOL licenses, which can be used in numerical simulations of the hydrodynamic behavior of multiphase systems. The research group at deals with the topic also experimentally, and is therefore able to provide the necessary experimental data to verify the results of numerical simulations.

Requirements for the applicant: master degree in chemical or mechanical engineering; ability to teamwork; systematic and creative approach to scientific problems; interest in experimental work.
