Paper Abstract

Quantitative velocity and turbulence measurements which were obtained using laser Doppler velocimetry during the course of the physical modeling of the molten aluminum flow in a tundish are presented. The experimental findings are compared to the results obtained by the computational simulation of the flow, showing favorable agreement between the two approaches. The measurements revealed asymmetric velocity and non-isotropic turbulence field near the nozzle exit. In the vicinity of the nozzle, the interaction of the impinging jet and the inclined walls gives rise to recirculating vortex structures. Downstream of the nozzle, two counter-rotating secondary cells diminish in strength.
