title = "Turbulent instabilities in a thin slab mold",
abstract = "A water-physical model of a funnel-type thin slab mold fed by a 2 ports SEN was employed to characterize the flow of liquid steel using dye tracer, PIV and video recording experiments. A cyclic and energetic flow distortion of short live inducing high meniscus oscillation was identified. Its intensity grows with high casting speeds of 7 m/min and at a shallow immersion position of a SEN. This distortion is originated by the apparent existence of vortex (lows located below the two discharging jets which are formed by the existence of shear stresses in their ends and acting on the surrounding fluid. It is inferred, under the ground of experimental results, that this flow distortion is originated by an instantaneous unbalance of the turbulent kinetic energy in the discharging jets. Negative production of kinetic energy is ascribed as the source of this unbalance which is compensated by higher contribution of the turbulent kinetic energy by mean convection and turbulent transport mechanisms manifested through higher velocities. After the restoration of the energy balance the system yields a stable meniscus to repeat the cycle.",
