N2 - Transient fluid flow behavior in a tundish with two different arrangements, a bare tundish and a tundish using flow control devices, was studied using physical modeling and a mathematical model. The study places special emphasis on buoyancy effects, particularly transient buoyancy effects due to step change in inlet temperature. For the bare tundish case, the inertial forces are strongly dominant, while in the arrangement using flow control devices, tundish with turbulence inhibitor and low dams, the buoyancy forces are dominant. The results were compared to those representing the real behavior, considering temperature variations, for each tundish arrangement. This comparison made possible the determination of the probable implicit error that could be present in the estimation of the fluid flow characteristic behavior used for the design of the tundish geometry and flow control devices when the temperature variations are not considered.
