Modelling binary alloy solidification with Adaptive Mesh Refinement
Journal of Computational Physics: X
A B S T R A C T The solidification of a binary alloy results in the formation of a porous mushy layer, within which spontaneous localisation of fluid flow can lead to the emergence of features over a range of spatial scales. We describe a finite volume method for simulating binary alloy solidification in two dimensions with local mesh refinement in space and time. The coupled heat, solute, and mass transport is described using an enthalpy method with flow described by a Darcy-Brinkman equationdoi:10.1016/j.jcpx.2019.100043 fatcat:5qmmj2ty2vddpmyvmqgikcpjau
