SIMULAÇÃO MATEMÁTICA DO ESCOAMENTO BIFÁSICO NO DISTRIBUIDOR DE LINGOTAMENTO CONTÍNUO: ESTUDO DO EFEITO DA SUBSTITUIÇÃO DA BARRAGEM POR CORTINA DE GÁS

Continuous casting is a solidification process, in which the knowledge about its variables is very important in order\udto produce steel with good quality. The tundish distributes the steel coming from the ladle to the metallurgical mold as\udthe traditional function, besides, it also has some other important functions. Because of its importance in the process, this\udwork aim to carry out studies on the steel flow in the tundish with two different configurations, with and without inert\udgas injection. A Computational Fluid Dynamic (CFD) software were used to make the mathematical simulations making\udpossible to note the difference in terms of the Residence Time Distribution curves (RTD curves), levels of turbulence and\udvelocity profiles with or without inert gas injectio
