Electron cyclotron drift instability and anomalous transport: two-fluid moment theory and modeling
Liang Wang, Ammar Hakim, Bhuvana Srinivasan +1
In the presence of a strong electric field perpendicular to the magnetic field, the electron cross-field (EB) flow relative to the unmagnetized ions can cause the Electron…
Curved boundary conditions of the lattice Boltzmann method for simulating microgaseous flows in the slip flow regime
Liang Wang, Shi Tao, Junjie Hu +2
The lattice Boltzmann method (LBM) has shown its promising capability in simulating microscale gas flows. However, the suitable boundary condition is still one of the critical issu…
Receptivity and stability of hypersonic leading-edge sweep flows around a blunt body
Youcheng Xi, Jie Ren, Liang Wang +1
This study performs global stability/receptivity analyses of hypersonic sweep flows around a blunt body with an infinite span. For the first time, we obtain the characteristics of…
Exact and Locally Implicit Source Term Solvers for Multifluid-Maxwell Systems
Liang Wang, Ammar Hakim, Jonathan Ng +2
Recently, a family of models that couple multifluid systems to the full Maxwell equations draw a lot of attention in laboratory, space, and astrophysical plasma modeling. These mod…
Discrete effect on the anti-bounce-back boundary condition of lattice Bhatnagar-Gross-Krook model for convection-diffusion equations
Liang Wang, Xuhui Meng, Hao-Chi Wu +2
The discrete effect on the boundary condition has been a fundamental topic for the lattice Boltzmann method in simulating heat and mass transfer problems. In previous works based o…
Global Ten-Moment Multifluid Simulations of the Solar Wind Interaction with Mercury: From the Planetary Conducting Core to the Dynamic Magnetosphere
Chuanfei Dong, Liang Wang, Ammar Hakim +4
For the first time, we explore the tightly coupled interior-magnetosphere system of Mercury by employing a three-dimensional ten-moment multifluid model. This novel fluid model inc…
Role of the Plasmoid Instability in Magnetohydrodynamic Turbulence
Chuanfei Dong, Liang Wang, Yi-Min Huang +2
The plasmoid instability in evolving current sheets has been widely studied due to its effects on the disruption of current sheets, the formation of plasmoids, and the resultant fa…
Electron Physics in 3D Two-Fluid Ten-Moment Modeling of Ganymede's Magnetosphere
Liang Wang, Kai Germaschewski, Ammar Hakim +3
We studied the role of electron physics in 3D two-fluid 10-moment simulation of the Ganymede's magnetosphere. The model captures non-ideal physics like the Hall effect, the electro…
Lattice Boltzmann simulation of separation phenomenon in a binary gaseous flow through a microchannel
Liang Wang, Zimian Xu, Zhaoli Guo
Gas separation of a binary gaseous mixture is one of characteristic phenomena in the micro-scale flows that differ from the conventional size flows. In this work, the separation in…
The island coalescence problem: scaling of reconnection in extended fluid models including higher-order moments
Jonathan Ng, Yi-Min Huang, Ammar Hakim +5
As modeling of collisionless magnetic reconnection in most space plasmas with realistic parameters is beyond the capability of today's simulations, due to the separation between gl…
