Upscaling the Navier-Stokes-Cahn-Hilliard model for incompressible multiphase flow in inhomogeneous porous media
Chunhua Zhang, Peiyao Liu, Cheng Peng +2
This work presents a macroscopic model for the flow of two immiscible and incompressible fluids within inhomogeneous porous media. At the pore scale, the flow is governed by the fu…
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…
Numerical study of three-dimensional single-mode Rayleigh-Taylor instability in turbulent mixing stage
Bin Liu, Chunhua Zhang, Qin Lou +1
Rayleigh-Taylor instability (RTI) as a multi-scale, strongly nonlinear physical phenomenon which plays an important role in the engineering applications and scientific research. In…
On the formulations of interfacial force in the phase-field-based lattice Boltzmann method
Chunhua Zhang, Hong Liang, Zhaoli Guo
Different formulations of interfacial force have been adopted in phase-field-based lattice Boltzmann method for two-phase flows. Although they are identical mathematically, their n…
Spontaneous shrinkage of droplet on wetting surface in phase-field model
Chunhua Zhang, Zhaoli Guo
Phase field theory is widely used to model multi-phase flows. A drop can shrink or grow spontaneously due to the redistribution of interface and bulk energies to minimize the syste…
Local reactive boundary scheme for lattice Boltzmann method
Long Jv, Chunhua Zhang, Zhaoli Guo
In this paper, a boundary scheme is proposed for the two-dimensional five-velocity (D2Q5) lattice Boltzmann method with heterogeneous surface reaction, in which the unknown distrib…
