Abstract: Transport phenomena of the molten steel in a twin-roll strip casting pool have been studied numerically by solving the momentum equation, k-ε two equations along with the species concentration equation. Flow and mixing characteristics of molten steel in the pool was analyzed using a V-type delivery system. Turbulence kinetic energy and residence time distribution (RTD) of the fluid near the free surface were calculated. It was shown that fluid can be uniformly distributed which was benefit to uniform solidification of the strip. The regeneration rate of fluid and level fluctuation increased near side dams. This is desirable to prevent formation of crust.
