In conclusion, it can be mentioned that a generalized formulation procedure for evaluation of latent heat functions as applicable to enthalpy-based solidification modeling of multicomponent alloy systems has been developed in the current study. The algorithm, in general, can be applied for latent heat updating in enthalpy-based methods for more accurate macroscopic models of multicomponent alloy solidification to follow in future studies.

The Fluctuations in Slag Foam Under Dynamic Conditions ABHA KAPILASHRAMI, ASHOK KUMAR LAHIRI, MÅRTEN GÖRNERUP, and SESHADRI SEETHARAMAN In the present article, slag foaming phenomenon under dynamic conditions is critically analyzed on the basis of the results of high-temperature X-ray image analysis experiments. The results indicate that the mismatch between the gas generation rate and gas escape rate has a serious impact
