Numerical Analysis on Fluid Dynamic Phenomena in a Strip Caster Mold by L.E.S.
Shinji KAJIWARA, Kunihiko ONISHI
This report presents the simulation results of flow patterns of liquid metal in a twin roll strip caster. To analyze the velocity field in liquid pool, the influence of the nozzle flow and free surface were considered. The large eddy simulation-L.E.S.-model was applied to handle the turbulence of flow. The fluctuation of the fluid was measured using the full size water model test apparatus as well. The influence of nozzle flow on the flow pattern was clarified. In the pool the fluctuation of flow depends on casting speed, submerged nozzle type, and so on. The fluctuation of flow changes with the hole type of submerged nozzle.
