Abstract
Air entrainment during mold filling leads to oxide inclusions that can severely diminish the mechanical properties of castings. Despite this, the volume of air that is entrained during pouring of liquid metals has never been quantified. The present research focuses on air entrainment for a liquid aluminum alloy jet plunging into a pool. Experimental measurements with argon and air atmospheres are performed to determine the total volume of gas entrained during pouring and the volume of oxygen consumed. They are used to validate a previously developed model that predicts air entrainment as part of a casting simulation . The measured entrainment ratios from the experiments conducted in an argon atmosphere are in approximate agreement with the previously developed model. A large difference between entrainment ratios for argon and air atmospheres is found.
