WebbFree-surface flow simulations require high-resolution grids to capture phenomena at the interface as well as a long computational time. In this paper, we propose a numerical method for realizing large-scale free-surface flow simulations using the lattice Boltzmann method and multiple GPUs. By introducing the adaptive mesh refinement (AMR) method, … Webb26 dec. 2024 · The SHSLBM is a recently developed scheme within lattice Boltzmann framework, which utilizes lattice properties and relationships given by Chapman-Enskog expansion analysis to reconstruct solutions of macroscopic governing equations recovered from lattice Boltzmann equation and resolved in a predictor-corrector scheme.
Webb28 okt. 2016 · The Lattice Boltzmann is not a meshless method. Actually, when looking at it, it is a finite difference method on an homogenous structured Cartesian grid (dx = dy = dz). However, the variables solved for are not the primary variables (U and P), but are pseudo-populations f i where i ∈ [ 1, n p] and where n p is the number of population in the …
WebbThis article proposes a phase-field-simplified lattice Boltzmann method (PF-SLBM) for modeling solid-liquid phase change problems within a pure material. The PF-SLBM consolidates the simplified lattice Boltzmann method (SLBM) as the flow solver and the phase-field method as the interface tracking algorithm. ctcl fundingWebbWe present the development of a non-reflecting boundary condition, based on the Local One-Dimensional Inviscid (LODI) approach, for Lattice Boltzmann Models working with multi-speed stencils.
