About this title

Synopsis

The lattice Boltzmann method (LBM) is a modern numerical technique, very efficient, flexible to simulate different flows within complex/varying geome­ tries. It is evolved from the lattice gas automata (LGA) in order to overcome the difficulties with the LGA. The core equation in the LBM turns out to be a special discrete form of the continuum Boltzmann equation, leading it to be self-explanatory in statistical physics. The method describes the micro­ scopic picture of particles movement in an extremely simplified way, and on the macroscopic level it gives a correct average description of a fluid. The av­ eraged particle velocities behave in time and space just as the flow velocities in a physical fluid, showing a direct link between discrete microscopic and continuum macroscopic phenomena. In contrast to the traditional computational fluid dynamics (CFD) based on a direct solution of flow equations, the lattice Boltzmann method provides an indirect way for solution of the flow equations. The method is characterized by simple calculation, parallel process and easy implementation of boundary conditions. It is these features that make the lattice Boltzmann method a very promising computational method in different areas. In recent years, it receives extensive attentions and becomes a very potential research area in computational fluid dynamics. However, most published books are limited to the lattice Boltzmann methods for the Navier-Stokes equations. On the other hand, shallow water flows exist in many practical situations such as tidal flows, waves, open channel flows and dam-break flows.

About the Author

Dr. Jian Guo Zhou graduated from Wuhan University with first degree in River Mechanics and River Engineering and subsequently finished his MSc in Hydraulics and Fluvial Mechanics at Tsinghua University. He received his PhD  in Fluid Mechanics from Leeds University. Since then, he has been working in computational fluid dynamics. His representative contributions are the surface gradient method for the treatment of the source terms in shallow water equations, the elastic-collision scheme for slip/semi-slip boundary conditions for lattice Boltzmann methods, the centered scheme for the force terms in the lattice Boltzmann equation, and lattice Boltzmann methods for shallow water equations with or without turbulence modelling.
