Numerical Simulation on Fluid Flow in Hot Metal Pretreatment

摘要：

Basing on the commercial CFD method, several models are adopted to simulate water model. The numerical simulation results are in good agreement with the experimental data of water model under the same experimental conditions. Then the numerical simulation method is presented to investigate the flow field, the vortex on gas-liquid surface and the uniform mixing time in hot metal ladles. This research shows: the vortex depth increases with increasing of immersion depth and rotation speed; Overflow appears in AN120rpm and A=3.2m; the turbulent kinetic energy increases with increasing immersion depth and rotation speed; uniform mixing time decreases with the decreasing of immersion depth and the rotation speed of stirring; the optimal uniform mixing time is 23.5s on the conditions of Af= 100rpm and h=3.2m within the allowable range.
