In this paper, the 3DQ19 model of Lattice Boltzmann Method (LBM) was employed to simulate the flow in the curved square duct with curvature ratio (0.2–2.0) and Dean Number (0 – 250). The so-called Dean instability in the curved square duct is fully investigated and a stability diagram is obtained in the domain of curvature ratio and Dean number. It is found that for the square duct with high curvature ratio the onset of transition from single vortex pair to double vortex pairs depends on the Dean number and curvature ratio, while at the small curvature the onset can be characterized by the Dean number alone. This trend is consistent with the conventional Computational Fluid Dynamic (CFD) and experimental results, and the differences between those are very small. For the friction coefficient, which is a function of Dean number, it is found that the numerical results are in good agreement with the available experimental data and conventional CFD results within the given parameters in this project.
