Numerical Simulation of Gas-Liquid-Solid Three Phase in Bubble Column

Abstract Based on the Euler-Euler-Lagrangian framework, Euler-Euler two-fluid model coupled with population balance (PBM) and Discrete Phase Model (DPM) were used to simulate gas-liquid-solid three phase dynamic behavior in laboratory bubble column. The non-Newtonian properties of liquid was considered numerical simulation, cases different models discussed. It is found that peak value velocity decrease due solid phase. gas holdup remains almost same or without There no obvious periodic oscillation plume fluid. interaction between has an effect flow field, distribution viscosity distribution. field calculated by CFD+PBM+DPM forms vortices, while symmetrical vortex formed model, which located both sides simulated basically vary cases.
