AN INTERFACE-TRACKING CONTROL-VOLUME FINITE-ELEMENT METHOD FOR MELTING AND SOLIDIFICATION PROBLEMS- PART II: VERIFICATION AND APPLICATION

Abstract

In a prior article, an interface-tracking control-volume-based finite-element method (CVFEM) for moving-boundary problems has been presented [1]. In this article, the numerical method is verified by applying it to basic isothermal melting and solidification problems. Numerical results are compared to analytical solutions, experimental data, and numerical benchmark solutions from the literature. They demonstrate the capabilities of the code to reproduce known solutions even when complex flow patterns and/or interface structures are present. Thus, the proposed adaptive front-tracking procedure is supposed to be an attractive alternative to the commonly used fixed-grid methods.
