Macroscopic Lattice Boltzmann Method [PDF]

Water, 2020
The lattice Boltzmann method (LBM) is a highly simplified model for fluid flows using a few limited fictitious particles. It has been developed into a very efficient and flexible alternative numerical method in computational physics, demonstrating its great power and potential for resolving more and more challenging physical problems in science and ...

Application of Regularized Lattice Boltzmann Method for Incompressible Flow Simulation at High Reynolds Number and Flow with Curved Boundary

Journal of Fluid Science and Technology, 2011
Single-relaxation time lattice Boltzmann method lacks the required numerical stability for high Reynolds number flow simulations. The method is also restricted to Cartesian grid, making it difficult to be implemented in flow with curved boundary ...

Efficient kinetic method for fluid simulation beyond the Navier-Stokes equation [PDF]

, 2006
We present a further theoretical extension to the kinetic theory based formulation of the lattice Boltzmann method of Shan et al (2006). In addition to the higher order projection of the equilibrium distribution function and a sufficiently accurate Gauss-

Simulations of time harmonic blood flow in the Mesenteric artery: comparing finite element and lattice Boltzmann methods

BioMedical Engineering OnLine, 2009
Background Systolic blood flow has been simulated in the abdominal aorta and the superior mesenteric artery. The simulations were carried out using two different computational hemodynamic methods: the finite element method to solve the Navier Stokes ...

The lattice Boltzmann method for wind farm simulations: a review [PDF]

Wind Energy Science
High-fidelity numerical simulations are currently a key method to gain insight into flows in very large wind farms. However, these simulations are extremely costly in terms of computational resources, and the progress in computational efficiency has been

Modelling thermal flow in a transition regime using a lattice Boltzmann approach [PDF]

, 2007
Lattice Boltzmann models are already able to capture important rarefied flow phenomena, such as velocity-slip and temperature jump, provided the effects of the Knudsen layer are minimal.
