Abstract	RESUMO – Historicamente, os processos siderurgicos estao vinculados ao desenvolvimento tecnico e industrial de uma nacao e estao atrelados a quantidade e a qualidade do aco produzido. Um dos equipamentos importantes neste processo, o canal de alto-forno, cuja funcao principal e extravasar o metal do altoforno, sofre desgaste de seu revestimento refratario parte fundamental de sua durabilidade e pouco se sabe como este processo ocorre. A metodologia apresentada neste trabalho modela o sistema ar-gusa considerando tanto o jato aberto quanto a superficie livre, alem da sua natureza transiente e turbulenta. O simulador ANSYS CFX foi empregado na solucao do sistema de equacoes. Os resultados indicam que o carater vorticoso e oscilatorio na regiao de impacto do jato aumentam os niveis energia cinetica turbulenta, a qual apresenta correlacao com a taxa de desgaste, permitindo estimar o seu perfil, e contradizem a crenca de que as tensoes cisalhantes sao as principais responsaveis por este processo.
