The lattice Boltzmann equation: theory and applications

Diffusion and hydrodynamic dispersion with the lattice Boltzmann method

A simple reinterpretation of the lattice Boltzmann equation is presented that allows it to track passive scalar dynamics in grossly irregular geometries without adding any new i...

LBE SIMULATIONS OF RAYLEIGH-BÉNARD CONVECTION ON THE APE100 PARALLEL PROCESSOR

In this paper we describe an implementation of the Lattice Boltzmann Equation method for fluid-dynamics simulations on the APE100 parallel computer. We have performed a simulati...

Two-dimensional turbulence with the lattice Boltzmann equation

The authors investigate the ability of the lattice Boltzmann equation to reproduce the basic physics of fully turbulent two-dimensional flows and present a qualitative estimate ...

Extended self-similarity in numerical simulations of three-dimensional anisotropic turbulence

Using a code based on the lattice Boltzmann equation, we have performed numerical simulations of a turbulent shear flow. We investigate the scaling behavior of the structure fun...

The mechanism of stochastic resonance

It is shown that a dynamical system subject to both periodic forcing and random \nperturbation may show a resonance (peak in the power spectrum) which is absent when \neither th...

Stochastic resonance in climatic change

An amplification of random perturbations by the interaction of non-linearities internal to the climatic system with external, orbital forcing is found. This stochastic resonance...
