Benchmarking of Massively Parallel Phase-Field Codes for Directional Solidification
Jiefu Tian, David Montiel, Kaihua Ji +4
We present a detailed benchmark comparing two state-of-the-art phase-field implementations for simulating alloy solidification under experimentally relevant conditions. The study i…
Phase-Field Model of Freeze Casting
Kaihua Ji, Alain Karma
Directional solidification of water-based solutions has emerged as a versatile technique for templating hierarchical porous materials. However, the underlying mechanisms of pattern…
Parity Breaking at Faceted Crystal Growth Fronts during Ice Templating
Kaihua Ji, Alain Karma
Directional solidification of water-based solutions has emerged as a versatile technique to template hierarchical porous materials, but this nonequilibrium process remains incomple…
Phase-field model of alloy solidification far from chemical equilibrium at the solid-liquid interface
Kaihua Ji, Mingwang Zhong, Alain Karma
We further develop a recently introduced phase-field model of rapid alloy solidification [Ji et al., PRL 2023]. This model utilizes enhanced solute diffusivity within the spatially…
Cell Invasion during Competitive Growth of Polycrystalline Solidification Patterns
Younggil Song, Fatima L. Mota, Damien Tourret +5
Spatially extended cellular and dendritic array structures forming during solidification processes such as casting, welding, or additive manufacturing are generally polycrystalline…
Microstructural Pattern Formation during Far-from-Equilibrium Alloy Solidification
Kaihua Ji, Elaheh Dorari, Amy J. Clarke +1
We introduce a new phase-field formulation of rapid alloy solidification that quantitatively incorporates nonequilibrium effects at the solid-liquid interface over a very wide rang…
Anti-rumor dynamics and emergence of the timing threshold on complex network
Kaihua Ji, Jiawei Liu, Gang Xiang
Anti-rumor dynamics is proposed on the basis of rumor dynamics and the characteristics of anti-rumor dynamics are explored by both mean-field equations and numerical simulations on…
