Multiphase Lattice Boltzmann Methods: Theory and Application | Wiley Online Books

Chinese Science Bulletin. November , Cite as. The lattice Boltzmann method LBM , a mesoscopic method between the molecular dynamics method and the conventional numerical methods, has been developed into a very efficient numerical alternative in the past two decades. Unlike conventional numerical methods, the kinetic theory based LBM simulates fluid flows by tracking the evolution of the particle distribution function, and then accumulates the distribution to obtain macroscopic averaged properties. In this article we review some work on LBM applications in engineering thermophysics: 1 brief introduction to the development of the LBM; 2 fundamental theory of LBM including the Boltzmann equation, Maxwell distribution function, Boltzmann-BGK equation, and the lattice Boltzmann-BGK equation; 3 lattice Boltzmann models for compressible flows and non-equilibrium gas flows, bounce back-specular-reflection boundary scheme for microscale gaseous flows, the mass modified outlet boundary scheme for fully developed flows, and an implicit-explicit finite-difference-based LBM; and 4 applications of the LBM to oscillating flow, compressible flow, porous media flow, non-equilibrium flow, and gas resonant oscillating flow.

Modelling multicomponent fluid flows with the lattice Boltzmann method

Essentials Of Computational Fluid Dynamics Pdf

Instead of solving the Navier—Stokes equations directly, a fluid density on a lattice is simulated with streaming and collision relaxation processes [1]. Also, fluids in complex environments such as porous media can be straightforwardly simulated, whereas with complex boundaries other CFD methods can be hard to work with. LBM is a relatively new [ when? Unlike the traditional CFD methods, which solve the conservation equations of macroscopic properties i. Due to its particulate nature and local dynamics, LBM has several advantages over other conventional CFD methods, especially in dealing with complex boundaries, incorporating microscopic interactions, and parallelization of the algorithm. The numerical methods of solution of the system of partial differential equations then give rise to a discrete map, which can be interpreted as the propagation and collision of fictitious particles. In an algorithm, there are collision and streaming steps.

The Journal of Computational Physics focuses on the computational aspects of physical problems. Essentials of Computational Fluid Dynamics provides a solid introduction to the basic principles of practical CFD and serves as a resource for students in mechanical or aerospace engineering taking a first CFD course as well as practicing professionals needing a brief, accessible introduction to CFD. Fluid Dynamics: Theoretical and Computational Approaches, Second Edition Book Title :Fluid Dynamics: Theoretical and Computational Approaches, Second Edition Fluid Dynamics presents the basic development of equations in coordinateinvariant form and their use in solving problems in laminar and turbulent flows. How would one explain the basic concept to an undergrad friend?. CFD made possible by the advent of digital computer and advancing with improvements of computer resources flops, 20 teraflops, 1. Computational physics is the study and implementation of numerical analysis to solve problems in physics for which a quantitative theory already exists. A process model which uses first principles to describe a chemical process is a good example.
