Abstract
A mathematical representation has been developed for the filling of cylindrical molds, using a bottom pouring arrangement. In the model allowance has been made for thermal natural convection, solidification and for the presence of the free surface. Turbulence was represented by assigning artificially enhanced parametric values to the viscosity and the thermal conductivity. The results have shown that the temperature profiles are markedly non-uniform, and that solidification would commence quite soon after the pouring process has been initiated. For the conditions considered, the free surface disturbances were not very great, although quite high free surface velocities were predicted by the model.
