In this study, a thin angular airfoil was optimized to improve aerodynamic performance under Reynolds number 10000. Unsteady CFD computation on Cartesian mesh with level set method was used to predict time-averaged aerodynamic performance. Through the optimization, it is concluded that the existence of laminar separation bubble highly affects the lift caused by the maximum camber position.
