Journal ArticleDOI
Viscous flow computations with the method of lattice Boltzmann equation
TL;DR: In this paper, the lattice Boltzmann equation (LBE) is applied to high Reynolds number incompressible flows, some critical issues need to be addressed, noticeably flexible spatial resolution, boundary treatments for curved solid wall, dispersion and mode of relaxation, and turbulence model.
Journal ArticleDOI
Force evaluation in the lattice Boltzmann method involving curved geometry
TL;DR: Two approaches for force evaluation in the lattice Boltzmann equation are investigated: the momentum-exchange method and the stress-integration method on the surface of a body, both reliable, accurate, and easy to implement for both two-dimensional and three-dimensional flows.
Journal ArticleDOI
Lattice Boltzmann Method for 3-D Flows with Curved Boundary
TL;DR: In this article, three athermal 3D LBE models (Q15D3, Q19D3 and Q27D3) are compared in terms of efficiency, accuracy, and robustness.
Journal ArticleDOI
A multi-block lattice Boltzmann method for viscous fluid flows
Dazhi Yu,Renwei Mei,Wei Shyy +2 more
TL;DR: In this paper, a multi-block LBE method for viscous flow computations is proposed. But it requires high resolution near the body and/or there is a far-field boundary.
