Multiphase Fluid Flow and Mixing Phenomena of the Molten Steel during RH Vacuum Refining Process
A three-dimensional mathematical coupled VOF and DPM models were applied to study the gas-liquid two-phase flow pattern characteristics during the RH refining process.The modified k-ε model was employed for turbulence.To validate the numerical calculation,a water model was established and the flow field was measured using a particle image velocimetry(PIV)system.The simulated velocity distribution showed a good agreement with the experimental results.The gas distribution and the plume area in the up-leg snorkel were computed.Turbulence characteristics and the wall shear stress in the full RH system were calculated.In addition,the recirculation rate and the mixing time were predicted.The current developed model can be used to evaluate and optimize RH degassing process.
