Fluid Flow Description in the Vicinity of a Liquid Steel / Slag Interface
The present work provides some data on the fluid flow characteristic near a liquid-liquid interface.A water model of continuous casting mold is used.Slag layer is represented by silicon oil.Measurements are realized by laser Doppler anemometer.A viscous sublayer below the interface is detected.Its y+ depth,based on the interfacial shear stress,is approximately 9,which is larger than the corresponding viscous sublayer for a wall.Very large values of the RMS are also measured.The shear stress is only slightly affected by the two values of the oil viscosity that we tested (2×10-5m2/s and 35×10-5m2/s).A simplified model is proposed and shows that the shear stress increases by only 20%when the viscosity goes from 2×10-5m2/s to 35×10-5m2/s.
