چکیده
The semi-Lagrangian Vortex method (VM) and the Lattice Boltzmann (LBM) are used to investigate flows simulations in incompressible regime. In this study, a proven version of each is compared on different three dimensional benchmarks terms numerical accuracy, convergence, diffusion dissipation. first comparisons made convected vortex study compare dissipation LBM VM. Then Taylor–Green investigated rate kinetic energy method. It shown that both methods converge same solution but way. VM performs better than for lowest resolution whereas appears be more accurate growing resolutions. These results confirmed 3D with wall boundaries stiff test case wake behind cube at Re=290 Re=570.

External and Internal Incompressible Viscous Flows Computation using Taylor Series Expansion and Least Square based Lattice Boltzmann Method
The lattice Boltzmann method (LBM) has recently become an alternative and promising computational fluid dynamics approach for simulating complex fluid flows. Despite its enormous success in many practical applications, the standard LBM is restricted to the lattice uniformity in the physical space. This is the main drawback of the standard LBM for flow problems with complex geometry. Several app...
متن کاملPreconditioned lattice-Boltzmann method for steady flows.
In this paper we propose a preconditioned lattice Boltzmann (LB) method for steady incompressible flows. For steady flows, the macroscopic equations derived from this LB model are equivalent to those from the standard LB model, but with an improved eigenvalue system. The proposed model can be viewed as an explicit solver for preconditioned compressible Navier-Stokes equations. Linear stability ...
متن کاملLattice-Boltzmann Method for Geophysical Plastic Flows
We explore possible applications of the Lattice-Boltzmann Method for the simulation of geophysical flows. This fluid solver, while successful in other fields, is still rarely used for geotechnical applications. We show how the standard method can be modified to represent freesurface realization of mudflows, debris flows, and in general any plastic flow, through the implementation of a Bingham c...
متن کاملLattice Boltzmann Method for Fluid Flows
We present an overview of the lattice Boltzmann method (LBM), a parallel and efficient algorithm for simulating single-phase and multiphase fluid flows and for incorporating additional physical complexities. The LBM is especially useful for modeling complicated boundary conditions and multiphase interfaces. Recent extensions of this method are described, including simulations of fluid turbulenc...
متن کاملA stencil adaptive phase-field lattice Boltzmann method for two dimensional incompressible multiphase flows
This paper presents a stencil adaptive phase-field lattice Boltzmann method (LBM) for the simulation of two-dimensional multiphase flows. In the phase-field model, the interface is viewed as a layer with finite thickness where physical parameters vary steeply and continuously. In the present study, a phasefield LBM is used. In this model, the Cahn–Hilliard equation can be correctly recovered by...
