Lees–Edwards Boundary Conditions for Lattice Boltzmann

摘要: Lees–Edwards boundary conditions (LEbc) for Molecular Dynamics simulations(1) are an extension of the well known periodic and allow simulation bulk systems in a simple shear flow. We show how idea LEbc can be implemented isothermal lattice Boltzmann simulations used to overcome problem maximum rate that is limited less then 1/L y (with L transverse system size) traditional implementations The only previous Lattice implementation LEbc(2) requires specific fourth order equilibrium distribution. In this paper we with usual quadratic distributions.
