N2 - Wall-resolved large-eddy simulation of a near-stall airfoil flow at Rec = 1.0×107 is conducted using the supercomputer Fugaku. The simulations provide the first high-fidelity database for such high-Reynolds number stall flows and therefore are valuable for understanding the turbulent airfoil stall phenomena and constructing a turbulence model. Compared to the previous LES at Rec = 2.1 × 106, the flowfield at Rec= 1.0 × 107 indicates typical Reynolds number effects, such as the decrease of the boundary layer thickness, delay of the turbulent flow separation, and the forward shift of the laminar-turbulent transition location.
