AbstractA CFD code "rFlow" based on the overlapping grids method was developed. An all speed numerical scheme SLAU combined with a fourth order MUSCL-type reconstruction is used to achieve high spatial resolutions. Dual-time stepping method is used for efficient implicit unsteady flow calculations. This paper reports on the two-dimensional results of the validations in the low speed and low Reynolds number flowfields. The obtained flowfield around a cylinder shows good agreement with experimental results where the size of the wake flow bubble and Karman vortex shedding are compared. Also, the calculated lift coefficients of a wing section are agreeable with the experimental data even at high incident angles.
