A unified multirate lattice Boltzmann framework for thermosolutal dendritic solidification
Yang Liu, Xiaomin Wu, Chengjie Zhan
Thermosolutal dendritic solidification involves interface evolution, solute diffusion, heat transfer, and melt flow over markedly different time scales. In lattice Boltzmann simula…
A diffuse-interface model for N-phase flows with liquid-solid phase change
Jiangxu Huang, Chengjie Zhan, Zhenhua Chai +2
In this work, we first propose a diffuse interface model for simulating N phase flows with solid liquid phase change. In this model, a phase field approach is adopted to capture mu…
A diffuse-interface method for the containerless freezing of three-phase flows in complex geometries
Jiangxu Huang, Chengjie Zhan, Zhenhua Chai +1
In this work, we first propose a diffuse-interface model for the freezing processes of three-phase flows in complex geometries, and the core of the model to intergratge the Navier-…
Phase-field-based lattice Boltzmann method for the transport of insoluble surfactant in two-phase flows
Chengjie Zhan, Hong Liang, Zhenhua Chai +1
In this work, we present a general second-order phase-field model for the transport of insoluble surfactant in incompressible two-phase flows. In this model, the second-order local…
