| Popis: | To simulate a continuous casting process the temperature and flow field during solidification of a pure metal in a moving slab is considered. The analysis includes natural convection effects in the liquid pool. Strong natural convection flows occur at Grashof numbers of 105–106. However, for the range of parameters investigated the natural convection had a negligible effect on the solid-liquid interface position. Various qualitative aspects of the combined forced and natural convection flow field in the liquid pool are presented. Even for very strong natural convection the effect of the flow field on the temperature field remains relatively minor, its predominant tendency is to enhance the formation of an almost isothermal region at the bottom of the pool. |
