CFD Simulation of Solid-Liquid Two-Phase Fluid Mechanics Characteristics During Pressurized Acid Leaching of Manganese Dust
The Euler-Euler(E-E)two-fluid model,Kinetic Theory of Granular Flow(KTGF),and k-εturbulence model were coupled to investigate the effects of agitation speed and solid volume fraction on the liquid phase velocity and turbulent kinetic energy within the reactor vessel.The results show that the liquid phase velocity and turbulent kinetic energy inside the vessel are positively correlated with the agita-tion speed and negatively correlated with the solid volume fraction.When the solid volume fractions are 2.5%,7%,and 13%,the corresponding reductions in liquid phase velocity are 8%,16.2%,and 18.4%,respectively,and the corresponding reductions in turbulent kinetic energy are 7.6%,13.2%,and 20.6%,respectively.
