Theory of the lattice boltzmann method
Webb30 juli 2015 · In this paper, we propose two initialization techniques for the lattice Boltzmann method. The first one is based on the theory of asymptotic analysis … Webb8 feb. 2013 · A thermal lattice Boltzmann model is constructed on the basis of the ellipsoidal statistical Bhatnagar–Gross–Krook (ES-BGK) collision operator via the Hermite moment representation. The resulting lattice ES-BGK model uses a single distribution function and features an adjustable Prandtl number.

WebbThe numerical stability of thermo-lattice Boltzmann (TLBE) models is presented.The TLBE algorithm is linearized and represented in matrix form. The spectral radius of the resulting matrix is obtained by the method of powers.

Webb1 juni 2000 · The lattice Boltzmann method (LBM) is coupled with the multiple-relaxation-time (MRT) collision model and the three-dimensional 19-discrete-velocity (D3Q19) … WebbThis unique professional volume is about the recent advances in the lattice Boltzmann method (LBM). It introduces a new methodology, namely the simplified and highly stable lattice Boltzmann method (SHSLBM), for constructing numerical schemes within the lattice Boltzmann framework.
WebbAs an important and fundamental problem in EHD, the behavior of freely-suspended liquid drops subjected to electrostatic fields was simulated with a 2-D LBM by means of the permittivity-density relation proposed by the authors and Peng’s multiphase LBM which can obtain high liquid-to-vapor density ratio and low liquid-phase compressibility.
WebbIn this paper, we propose a vector-type bounce-back boundary scheme for the lattice Boltzmann method based on vector-BGK models. The scheme is shown to have second-order accuracy if the boundary is located at the middle of two neighboring lattice nodes. hamish hastieWebbTimm Krüger is giving an introduction to lattice-Boltzmann method (LBM).
