This paper presents a compact and efficient finite-volume lattice Boltzmann formulation on three-dimensional unstructured grids based on a cell-vertex scheme. The resulting model has been tested against the laminar flow past a sphere at low Reynolds numbers.

Keywords:  Lattice Boltzmann method; Unstructured grids; Finite volumes; Fluid dynamics
