Abstract

A particle-free surface coupled model has been developed using the Eulerian–Eulerian approach for revealing the gas–steel–slag multiphase flow in the vacuum chamber of a 210-ton RH degasser. The particle submodel preferred to predict the gas–steel and gas–slag interpenetrating phenomena, while the free surface submodel focused on tracking the steel–slag interface flow. The mesh sensitivity analysis has been investigated, and the coupled model was validated by the measured values. Using this coupled model, some previously unknown problems about multiphase flow in the vacuum chamber were revealed, such as the effect of the free surface fluctuation, variation of the liquid level, and slag flow behavior.
