E-1: Multiscale Modeling of Solidification Processes for Metal & Alloys: Mohamad Daeipour1; Mohammad Ishtiyaq1; Ashok Gurung1; Serge Nakhmanson1; Harold Brody1; 1University of Connecticut
We implemented a general enthalpy method for simulating the melting and solidification of metals and alloys utilizing a highly scalable real-space finite-element-method (FEM) based approach. Initial model predictions for the process of Al-Cu alloy solidification were validated against analytical solutions and benchmarks available in the literature, producing excellent agreement. The model was then utilized to design a ‘digital twin’ for the aluminum alloy casting process and validate thermophysical input parameters for the casting mold. The model ability to predict the cast alloy microstructure was also evaluated. The developed model for the alloy solidification process is available as an open-source module for the MOOSE (Multiphysics Object-Oriented Simulation Environment) FEM framework and can be utilized for predicting cast alloy properties and behavior in advanced manufacturing settings.
