Validation of the Physical Simulations of a Stirred Molten Metal Using Particle Image Velocimetry Data

Abstract

Melt shearing refines the as-cast structure and the mechanism suggested beforehand is that of enhanced nucleation through oxide dispersion and fragmentation. The efficiency of processing by a rotor–stator mixer depends strongly on the treated volume of liquid metal. In this article the analytical modeling is validated by particle image velocimetry (PIV). The radius of the mixed region (a) has been described as a linear function of rotational speed (N) and the scale-up rules are given. Water model predictions have been confirmed experimentally by liquid metal shearing.
