An overview of boundary implementation in lattice boltzmann method for computational heat and mass transfer

Abstract

The ability to deal with the complex geometries precisely and accurately has always been the most integral part of any computational fluid dynamics approach. The lattice Boltzmann method has already achieved considerable success in the simulation of unsteady flow with arbitrary boundary shapes. To include boundaries in the lattice Boltzmann simulations, several methods have been presented in the past to satisfy the standard boundary implementation of macroscopic flows. In spite of the considerably vast body of literatures that discuss in this field, the study still is in progress. The current study is an overview of the adopted boundary conditions in lattice Boltzmann method.
