  turbulence inhibitor
Melt flow control in a multistrand tundish using a turbulence inhibitor
      
Three different cases were studied: a bare tundish (BT), a tundish with two pairs of baffles and a waved impact pad (BWIP), and a tundish equipped with turbulence inhibitor and a pair of dams (TI>amp;amp;D).
      
The use of a turbulence inhibitor yields plug flow volume fractions well above 40 pct for a casting rate of 3.12 tons/min under isothermal conditions.
      
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.
      
Similarly, RTD curves were obtained for tundish operations without and with a dam+turbulence inhibitor device (TID).
