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…
Phase-field modeling of dendritic growth with gas bubbles in the solidification of binary alloys
Chengjie Zhan, Zhenhua Chai, Dongke Sun +3
In this work, a phase-field model is developed for the dendritic growth with gas bubbles in the solidification of binary alloys. In this model, a total free energy for the complex…
