Simulation of a Two-Dimensional Channel Flow around Arbitrary Obstacle with the Lattice Boltzmann Method
نویسنده
چکیده
It is shown that the lattice Boltzmann automata (LBA) provides a viable numerical method for the study of two-dimensional channel flow around arbitrary obstacle. The LBA is built up on the D2Q9 model and a single relaxation time method called the lattice-BGK method. Numerical results based on an advanced lattice Boltzmann technique for a discrete microscopic description of a low Reynolds number flow in a two-dimensional channel flow are reported and its practical relevance is investigated by comparing it with the analytical result. It is found that this approach allows to improve the understanding of the flow pattern in highly complex geometries and to obtain a reliable database for their operating behaviour and design.
