Can we find steady-state solutions to multiscale rarefied gas flows within dozens of iterations?
Wei Su, Lianhua Zhu, Peng Wang +2
One of the central problems in the study of rarefied gas dynamics is to find the steady-state solution of the Boltzmann equation quickly. When the Knudsen number is large, i.e. the…

Yuan Yu, Haihu Liu, Dong Liang +1
We propose a lattice Boltzmann color-gradient model for immiscible ternary fluid flows, which is applicable to the fluids with a full range of interfacial tensions, especially in n…
A high-order hybridizable discontinuous Galerkin method with fast convergence to steady-state solutions of the gas kinetic equation
Wei Su, Peng Wang, Yonghao Zhang +1
The mass flow rate of Poiseuille flow of rarefied gas through long ducts of two-dimensional cross-sections with arbitrary shape are critical in the pore-network modeling of gas tra…
A multi-level parallel solver for rarefied gas flows in porous media
Minh Tuan Ho, Lianhua Zhu, Lei Wu +4
A high-performance gas kinetic solver using multi-level parallelization is developed to enable pore-scale simulations of rarefied flows in porous media. The Boltzmann model equatio…
A fast iterative scheme for the linearized Boltzmann equation
Lei Wu, Jun Zhang, Haihu Liu +2
An iterative scheme can be used to find a steady-state solution to the Boltzmann equation, however, it is very slow to converge in the near-continuum flow regime. In this paper, a…
