Bubble column dynamics with bubble induced turbulence and dispersion

The paper presents an evolution of developed mathematical model which is devoted to the description of turbulent flows of bubbly media. The model utilizes Euler-Euler approach which is expanded by k-ω-SST turbulence model with additional modifications, related to the bubble induced turbulence and bubble path dispersion. Numerical code based on the proposed model was developed to perform computation of bubble column evolution. Good agreement with experimental data was obtained, and necessity of inclusion of both modifications related to the turbulent motion was shown.
