Nonequilibrium and morphological characterizations of Kelvin-Helmholtz instability in compressible flows
Yanbiao Gan, Aiguo Xu, Guangcai Zhang +3
We investigate the effects of viscosity and heat conduction on the onset and growth of Kelvin-Helmholtz instability (KHI) via an efficient discrete Boltzmann model. Technically, tw…
Thermo-hydrodynamic non-equilibrium effects on compressible Rayleigh-Taylor instability
Huilin Lai, Aiguo Xu, Guangcai Zhang +3
The effects of compressibility on Rayleigh-Taylor instability (RTI) are investigated by inspecting the interplay between thermodynamic and hydrodynamic non-equilibrium phenomena (T…
Discrete Boltzmann modeling of multiphase flows: hydrodynamic and thermodynamic non-equilibrium effects
Yanbiao Gan, Aiguo Xu, Guangcai Zhang +1
A discrete Boltzmann model (DBM) is developed to investigate the hydrodynamic and thermodynamic non-equilibrium (TNE) effects in phase separation processes. The interparticle force…

We present a highly efficient lattice Boltzmann (LB) kinetic model for thermal liquid-vapor system. Three key components are as beow: (i) a discrete velocity model by Kataoka \emph…
Discrete Boltzmann modeling of liquid-vapor system
Aiguo Xu, Guangcai Zhang, Yanbiao Gan
We further probe the Discrete Boltzmann Modeling(DBM) of the single-component two phase flows or the liquid-vapor system. There are two kinds of nonequilibrium effects in the syste…
Lattice BGK kinetic model for high speed compressible flows: hydrodynamic and nonequilibrium behaviors
Yanbiao Gan, Aiguo Xu, Guangcai Zhang +1
We present a simple and general approach to formulate the lattice BGK model for high speed compressible flows. The main point consists of two parts: an appropriate discrete equilib…

Phase separation in thermal systems: LB study and morphological characterization
Yanbiao Gan, Aiguo Xu, Guangcai Zhang +1
We investigate thermal and isothermal symmetric liquid-vapor separations via a FFT-Thermal Lattice Boltzmann (FFT-TLB) model. Structure factor, domain size and Minkowski functional…
FFT-LB modeling of thermal liquid-vapor systems
Yanbiao Gan, Aiguo Xu, Guangcai Zhang +1
We further develop a thermal LB model for multiphase flows. In the improved model, we propose to use the FFT scheme to calculate both the convection term and external force term. T…
