摘要

The side-blowing smelting process for anode slime represents a notable advance in molten pool smelting technology. In this study, the gas–liquid two-phase flow within an anode slime side-blowing furnace was investigated using a multi-fluid volume of fluid (VOF) multiphase model. Guided by experimental data from an air–water side-blowing analog, appropriate interphase interaction and turbulence models were selected. A detailed analysis was conducted of the time-averaged distributions of flow regime, melt velocity, gas volume fraction, and wall shear stress within the molten pool. The results reveal that, along the tuyere axis, the melt velocity exhibits significant attenuation downstream of the tuyere outlet owing to momentum transfer toward the pool center. Concurrently, both the mean horizontal velocity of the melt and the gas holdup increase progressively with furnace height. Wall erosion is primarily concentrated near the tuyere outlet and in the region above it, close to the liquid surface. The most severe erosion occurs in the vicinity of the tuyere outlet, where the maximum wall shear stress reaches 509 Pa.
