The aim of the work reported here is to produce a computer program capable of describing the flow of steel in the tundish and mould during continuous casting. The behaviour of the program is studied as a function of variations imposed on the calculation mesh and the Reynolds number. Considering that in the real systems it is wished to represent, flows with Reynolds numbers in the 50,000 - 100,000 region are involved, it is obviously desirable to improve the method of solution to render it stable at these values. Moreover, it has been necessary to introduce models which take account of energy loss due to turbulence. Appropriate modifications made to the routine which determines the physical boundaries of the field within which flow occurs have permitted representation of steel flow in the tundish even in the presence of baffles. Finally the program is completed with the development of a new model that can predict the pattern of the thermal field within the domain as a function of temperatures of heat flows imposed as boundary conditions. This permits simulation within the tundish in the presence of a supplementary energy source, such as a plasma torch, positioned at the free surface.
