Abstract Scope |
How to obtain material parameters is a key issue when performing continuum-based numerical simulations for material microstructure evolution. One promising approach for obtaining material parameters is the data assimilation, which can incorporate experimental observations into numerical simulations. In this study, we focus on the dendrite growth problem in alloy solidification. We attempt to infer some material parameters, such as solid-liquid interface energy, its anisotropy, and diffusion coefficient, by developing a data assimilation system coupled with the phase-field method. Sequential data assimilation with ensemble Karman filter and particle filter is investigated to develop a better phase-field data assimilation system for inferring material parameters for dendrite growth problem. |
