Study of Processes of Additional Turbulence Generation in Two-Phase Flows with Large Particles

The fundamental possibility of studying the process of additional generation of turbulence in flows with large particles is demonstrated with a model based on the system of Reynolds-averaged Navier–Stokes (RANS) equations. Calculations of additional generation of turbulence in an ascending air flow with large particles were performed. The calculation results are compared with the available experimental data, taking into account the actual values of the mass concentration of particles.
