The use of aluminum alloys in many industrial sectors is still increasing today. Due to its excellent properties, aluminum is widely used, for example, in construction, food, and automotive industries. The increase in the use of aluminum is also accompanied by increasing demands for chemical and metallographic cleanliness of this metal. The presence of unwanted phases in the molten metal can cause changes in final castings properties, such as porosity, corrosion susceptibility, electrical and thermal conductivity, etc. These phases are represented especially by harmful gases and non-metallic inclusions. Although significant progress has been made in the field of metallurgy in recent decades, great attention is still being paid to the optimization of metallurgical processes. Refining technology of aluminum melts is not the exception. Reducing refining time and process intensification often results in significant financial savings. This work is focused on the actual phase of research and development of refining technology of aluminum melt by an inert gas, through numerical modelling in ANSYS Fluent simulation software.Keywords: Metallurgy, aluminum, numerical modelling, ANSYS Fluent
