On the lattice Boltzmann method for multiphase flows with large density ratios

is a reduced-order kinetic model to reproduce the Navier-Stokes hydrodynamics (and beyond) at a macroscopic level. Since the pioneering work of McNamura and Zanetti (1988), the LB method has been extended to various complex flows involving, for example, multicomponent and interfacial phenomena , and has been particularly successful for multiphase flows in complex geometry and porous media (Succ...

Multiple - Relaxation - Time Lattice Boltzmann Method for Multiphase Flows with High Density and Viscosity Ratios - 10135

In this paper, the lattice Boltzmann method is reviewed for specific applications to numerical simulation of multiphase flow problems. A thorough literature review regarding the multi-phase lattice Boltzmann method was conducted with special focus on flows with large density and viscosity ratios between the two phases. A multiphase model with the capability of handling large-density-ratios is c...

Axisymmetric multiphase lattice Boltzmann method.

A lattice Boltzmann method for axisymmetric multiphase flows is presented and validated. The method is capable of accurately modeling flows with variable density. We develop the classic Shan-Chen multiphase model [Phys. Rev. E 47, 1815 (1993)] for axisymmetric flows. The model can be used to efficiently simulate single and multiphase flows. The convergence to the axisymmetric Navier-Stokes equa...

Efficient GPGPU implementation of a lattice Boltzmann model for multiphase flows with high density ratios

We present the development of a Lattice Boltzmann Method (LBM) for the numerical simulation of multiphase flows with high density ratios, such as found in ocean surface wave and air–sea interaction problems, and its efficient implementation on a massively parallel General Purpose Graphical Processing Unit (GPGPU). The LBM extends Inamuro’s et al.’s (2004) multiphase method by solving the Cahn–H...

Chemical-potential-based lattice Boltzmann method for nonideal fluids.

Chemical potential, as an important thermodynamic quantity, has been popularly used in thermodynamic modeling for complex systems, especially for those involving the phase transitions and chemical reactions. Here we present a chemical-potential-based multiphase lattice Boltzmann model, in which the nonideal force is directly evaluated by a chemical potential. The numerical computation is more e...
