| Abstract: | Three dimensional turbulent viscous flow analyses for the mold in the continuous casting process are performed by solving Reynolds averaged Navier Stokes equations with a two equation turbulence model. A silicon oil/water model is used to represent the real slag/molten steel setup. The slag entrapment is simulated with the filling method. The influence of injected gas on entrapment of the mold powder is studied considering the fluctuation of the inlet flow velocity. Comparison of simulation results with experiment results of a water model is made and there exists good agreement between the numerical and measured results. |
