Abstract:
Results of the development of a mathematical model of turbulent flows in bubbly media are presented. The proposed model is based on the Euler-Euler approach to the description of multiphase flows, which is supplemented by the $k$–$\omega$-SST model of turbulence with some modifications that make possible (i) the generation of turbulence due to the relative motion of phases and (ii) the turbulence-induced dispersion of bubbles. Investigations performed using the proposed model and the corresponding numerical code provided detailed information on the structure of turbulent flows in bubble columns. The results of calculations show good coincidence with experimental data.
