The effects of the kinematic viscosity of slag on the fluid flow phenomena in a molten metal bath agitated by bottom gas injection was investigated using a cold model. Water and some silicone oils of different kinematic viscosities were used as models for the molten metal and slag, and air was used as a model for the injected gas. The liquid flow velocity was measured with a two channel laser Doppler velocimeter (LDV). The turbulence components were more influenced by the kinematic viscosity than the mean velocity components. Empirical equations were derived for the spatial mean kinetic energies of the mean velocity and turbulence components.
