A finite-volume method on unstructured grids for solving systems of conservation laws of compressible fluids is extended to chemically reacting non-equilibrium flow problems at very low Mach numbers. Convergence and accuracy is ensured by local preco

The lattice-BGK method has been extended by introducing additional, free parameters in the original formulation of the lattice-BGK methods. The relationship between these parameters and the macroscopic moment equations is analysed by Taylor series an

Lattice-Boltzmann models, proposed at the end of the 1980s as the noise-free version of lattice-gas models are based on gas-kinetical-like representation of fluid flow. Their recent modifications, the lattice-BGK models, provide especially simple, ef

This paper deals with the numerical simulation of three-dimensional gas-particle flow through filters. Typical for filter flows is the deposition of particles on the surfaces of filter material, resulting in irregular shapes of surfaces, which in int
