Finite-difference lattice Boltzmann model for liquid-vapor systems
A two-dimensional finite-difference lattice Boltzmann model for liquid–vapor systems is introduced and analyzed. Two different numerical schemes are used and compared in recovering equilibrium density and velocity profiles for a planar interface. We show that flux limiter techniques can be conveniently adopted to minimize spurious numerical effects and improve the numerical accuracy of the mode...
متن کاملFinite Difference Lattice Boltzmann Model for Liquid Vapour Systems
Lattice Boltzmann (LB) models [1,2,3,4,5] provide an alternative to current methods in computational fluid dynamics (CFD). Unlike conventional numerical techniques based on the discretization of the macroscopic fluid equations, LB models are based on the physics at the mesoscopic scale, while the macroscopic level phenomena are recovered from evolution equations which contain the force a F m = ...
متن کاملFinite-difference-based lattice Boltzmann model for dense binary mixtures.
We propose a finite-difference-based lattice Boltzmann model for dense binary mixtures based on the Enskog theory. The model is applicable to a mixture composed of two dense fluids with different shear viscosities. The macroscopic hydrodynamic and diffusion equations are derived from the model through the Chapmann-Enskog procedure. The model is also validated numerically.
متن کاملFinite-difference lattice Boltzmann model for nonlinear convection-diffusion equations
A lattice Boltzmann model for convection-diffusion equation with nonlinear convection and isotropic-diffusion terms is proposed through selecting equilibrium distribution function properly. The model can be applied to the common real and complex-valued nonlinear evolutionary equations, such as the nonlinear Schrödinger equation, complex Ginzburg-Landau equation, Burgers-Fisher equation, nonline...
متن کاملLow Mach Number Flows and Combustion
We prove uniform existence results for the full Navier-Stokes equations for time intervals which are independent of the Mach number, the Reynolds number and the Péclet number. We consider general equations of state and we give an application for the low Mach number limit combustion problem introduced by Majda in [18].
