| Abstract Scope |
Fluid dynamics greatly affects solidification microstructure in metal casting, welding, and additive manufacturing. On the other hand, the inclusion of fluid flow in materials processing models is hindered by the multidisciplinary expertise required, namely computational fluid dynamics (CFD), solidification, thermodynamics, computational science, and extraordinary computational resources needed for solving the complex physical system of equations. In solidification problems, the “solid” cells and the evolution of the solidification front poses several implementation problems related to Computational Fluid Dynamics (CFD) modeling. In this study, a CFD implementation of a Scalable Navier–Stokes–Brinkman (snsb) solver using projection method for the Navier-Stokes-Brinkman to simulate fluid flow in domains with embedded solids is presented. Several benchmarks are used to test and assess the convergence of several implementations. The snsb library was then linked to muMatScale, a cellular automata code for solidification microstructure prediction. Results for the convection-assisted solidification using the muMatScale-snsb model are presented. |
