The turbulent fluid flow was modelled by the Boussinesq analogy to evalute the Reynolds stress, and the turbulent viscosity was calculated by the k-e turbulence model. A computer program to soolve the tridimensional cartesian elliptic equations was developed using the control volume method approach. The velocity-pressure couppling was treated using the SIMPLEC algorithm. The algebric conservation equations were solved in a segregated way, using the TDMA line-by-line algorithm and a block correction was employed to acelerate convergence. The fluid flow was solved for a tundish without flow control and different configura tions with a weir and dam were also studied. The tome of residence inside the tundish was calculated and a cleanliness factor was adopted to quality diferent: configurations. The results were compared with solutions avaiable in the literature, showing an excelent comparison. It was shown that the use of a weir and a dam as flow control can be very atractive, as the time of residence inside the tundish is bigger, raising the probality of non-metalic inclusions separation.
