Lattice Boltzmann (LB) methods are usually developed on cubic lattices that discretize the configuration space using uniform grids. For efficient computations of anisotropic and inhomogeneous flows, it would be beneficial to develop LB algorithms involving the collision-and-stream steps based on orthorhombic cuboid lattices. We present a new 3D central moment LB scheme based on a cuboid D3Q27 lattice. This scheme involves two free parameters representing the ratios of the characteristic… 

Rectangular multiple-relaxation-time lattice Boltzmann method for the Navier-Stokes and nonlinear convection-diffusion equations: General equilibrium and some important issues

Central moment lattice Boltzmann method on a rectangular lattice

The ability of the proposed rectangular LBMs to simulate at relatively lower grid aspect ratios and higher Reynolds numbers than considered in prior approaches is demonstrated and simulations reveal the superior stability characteristics of the rectangular central moment LBM over that based on raw moments in handling shear at lower viscosities and/or higher characteristic velocities.

Rectangular Lattice-Boltzmann Schemes with BGK-Collision Operator

A rectangular scheme is constructed, with the BGK collision operator, by introducing 2 additional discrete velocities into the standard D2Q9 stencil and it is shown how the same procedure can be applied in three dimensions by extending the D3Q19 stencil.
