Discrete unified gas kinetic scheme for the conservative Allen-Cahn equation
Chunhua Zhang, Hong Liang, Zhaoli Guo +1
In this paper, the discrete unified gas kinetic scheme (DUGKS) with an improved microflux across the cell interface for the conservative Allen-Cahn equation (CACE) is proposed. In…

Isotropy and spurious currents in pseudo-potential multiphase lattice Boltzmann models
Cheng Peng, Luis F. Ayala, Orlando M. Ayala +1
The spurious currents observed in multiphase flow simulations with pseudo-potential lattice Boltzmann (LB) models are usually understood to be the result of the lack of isotropy of…

A comparative study of immersed boundary method and interpolated bounce-back scheme for no-slip boundary treatment in the lattice Boltzmann method: Part I, laminar flows
Cheng Peng, Orlando M. Ayala, Lian-Ping Wang
The interpolated bounce-back scheme and the immersed boundary method are the two most popular algorithms in treating a no-slip boundary on curved surfaces in the lattice Boltzmann…
