摘要: Abstract The flow pattern in a two-dimensional lid-driven semi-circular cavity is analyzed based on multiple relaxation time lattice Boltzmann method (MRT LBM) this paper. Reynolds number ranges from 5000 to 50000. Numerical results show that, as Re increases, the undergoes complex transition (from steady periodic flow, and finally chaotic flow). demonstrate superior numerical stability wildly applicability of MRT model high flow.
