High-Order Implicit Hybridizable Discontinuous Galerkin Method for the Boltzmann Equation
Wei Su, Peng Wang, Yonghao Zhang +1
The high-order hybridizable discontinuous Galerkin (HDG) method combining with an implicit iterative scheme is used to find the steady-state solution of the Boltzmann equation with…
Lattice Boltzmann simulation of viscous fingering of immiscible displacement in a channel using an improved wetting scheme
Yuan Yu, Haihu Liu, Yonghao Zhang +1
An improved wetting boundary implementation strategy is proposed based on lattice Boltzmann color-gradient model in this paper. In this strategy, an extra interface force condition…
On the apparent permeability of porous media in rarefied gas flows
Lei Wu, M. T. Ho, Lefki Germanou +4
The apparent gas permeability of the porous medium is an important parameter in the prediction of unconventional gas production, which was first investigated systematically by Klin…
A comment on `An improved macroscale model for gas slip flow in porous media'
Lei Wu, Minh Tuan Ho, Lefki Germanou +4
In a recent paper by Lasseux, Valdés-Parada and Porter (J.~Fluid~Mech. \textbf{805} (2016) 118-146), it is found that the apparent gas permeability of the porous media is a nonline…
A comparative study of discrete velocity methods for rarefied gas flows
Peng Wang, Minh-Tuan Ho, Lei Wu +2
In the study of rarefied gas dynamics, the discrete velocity method (DVM) has been widely employed to solve the gas kinetic equations. Although various versions of DVM have been de…
Lattice Boltzmann modelling of intrinsic permeability
Jun Li, Minh Tuan Ho, Lei Wu +1
Lattice Boltzmann method (LBM) has been applied to predict flow properties of porous media including intrinsic permeability, where it is implicitly assumed that the LBM is equivale…
Lattice ellipsoidal statistical BGK model for thermal non-equilibrium flows
Jianping Meng, Yonghao Zhang, Nicolas G. Hadjiconstantinou +2
A thermal lattice Boltzmann model is constructed on the basis of the ellipsoidal statistical Bhatnagar-Gross-Krook (ES-BGK) collision operator via the Hermite moment representation…
Kinetic diffuse boundary condition for high-order lattice Boltzmann model with streaming-collision mechanism
Jianping Meng, Yonghao Zhang
The implementation of the kinetic diffuse boundary condition with the characteristic streaming-collision mechanism is studied for the high-order lattice Boltzmann (LB) models. The…
Beyond the Knudsen number: assessing thermodynamic non-equilibrium in gas flows
Jianping Meng, Nishanth Dongari, Jason M. Reese +1
For more than 150 years the Navier-Stokes equations for thermodynamically quasi-equilibrium flows have been the cornerstone of modern computational fluid dynamics that underpins ne…
Multiscale lattice Boltzmann approach to modeling gas flows
Jianping Meng, Yonghao Zhang, Xiaowen Shan
For multiscale gas flows, kinetic-continuum hybrid method is usually used to balance the computational accuracy and efficiency. However, the kinetic-continuum coupling is not strai…
Accuracy analysis of high-order lattice Boltzmann models for rarefied gas flows
Jianping Meng, Yonghao Zhang
In this work, we have theoretically analyzed and numerically evaluated the accuracy of high-order lattice Boltzmann (LB) models for capturing non-equilibrium effects in rarefied ga…
