Analysis of lattice Boltzmann schemes with the Taylor expansion method

In this communication, we first familiarize the beginner with the underlying algorithms of multirelaxation lattice Boltzmann schemes. Then we present the Taylor expansion method, a general approach for the analysis of arbitrary nonlinear lattice Boltzmann schemes at second order accuracy. After this we introduce the so-called “Berlin algorithm” able to explicit the equivalent partial differential equations of an arbitrary linear lattice Boltzmann scheme at any order.
