Lattice Boltzmann methods and active fluids [PDF]
The European Physical Journal E, 2019 We review the state of the art of active fluids with particular attention to hydrodynamic continuous models and to the use of Lattice Boltzmann Methods (LBM) in this field. We present the thermodynamics of active fluids, in terms of liquid crystals modelling adapted to describe large-scale organization of active systems, as well as other effective ...

Modeling of natural convection by lattice Boltzmann in a partially heated cavity [PDF]
E3S Web of Conferences, 2023 This study introduces the lattice Boltzmann method for modeling natural convection in a partially heated square cavity filled with air for varying Rayleigh numbers. A temperature gradient affects the vertical walls, whereas the other walls are treated as

Parametric lattice Boltzmann method [PDF]
Journal of Computational Physics, 2017 The discretized equilibrium distributions of the lattice Boltzmann method are presented by using the coefficients of the Lagrange interpolating polynomials that pass through the points related to discrete velocities and using moments of the Maxwell-Boltzmann distribution.
