CFD modelling of gasliquid flow in an industrial scale

Sep 10, 2015 · A two fluid model is introduced to describe the bubbly flow in an industrial leaching tank. The validity of the model is proved by literature experimental data in a small scale airlift reactor. Slurry flow mixing and gas bubble distribution in the industrial leaching tank are mainly discussed.
