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…

A lattice Boltzmann model for the coupled cross-diffusion-fluid system
Chengjie Zhan, Zhenhua Chai, Baochang Shi
In this paper, we propose a lattice Boltzmann (LB) model for the generalized coupled cross-diffusion-fluid system. Through the direct Taylor expansion method, the proposed LB model…
