Lattice Boltzmann方法理论和应用的新进展

Advances in theory of Lattice Boltzmann Method and its appliction

与传统的计算流体动力学方法(如FDM,FEM等)相比,LatticeBoltzmann方法(LBM)具有算法简单、精度高、压力可以直接求解、能够模拟具有复杂边界条件的问题以及适合于并行计算等优点.边界条件处理和提高模拟流场Re的新方法,促进了LBM理论的发展和完善,并且在二维和三维的水力学、多相流、热传导以及对流 扩散问题的模拟中获得了广泛的应用.

Compared with the conventional methods in computational fluid dynamics, such as the FDM and FEM, the Lattice Boltzmann Method(LBM) has the following advantages: the algorithm is simple and accurate, the pressure can be solved directly, and the method can be used to solve problems with complex boundaries and especially fits to parallel computation. New ways developed to deal with the boundary conditions and enhance the Reynolds number in the simulation promote the development of the LBM. The LBM has been widely applied to the simulation of problems in hydrodynamics, multiphase flows, heat transfer, and convectiondiffusion in two or three dimensions.
