The objective of this study is to model the behaviour of a gas jet impacting a metal bath in order to protect its surface against oxidation. This process is often used in metallurgical industry. The gas and the liquid flows are modelled using the volumes of fluid technique (VOF). The equations of the problem are formulated using the density and the viscosity of the gas-liquid mixture which are expressed in terms of phase volume fractions. The k-ε model is used to describe the turbulence of gas. The equations of the problem are solved in cartesian coordinates using the commercial code CFD, Fluent. Focus is done in this work on speed and pressure field variations over the metallic bath surface as function of the gas jet rate, the jet inclination angle and the gas nature. The obtained results, according to various parametric studies, make it possible to analyze the modified morphology of the treated zone. The aim is obtaining the most regular possible metal bath surface after performing a gas jet treatment.
