Unstructured meshes are vastly applied in computational aerodynamics due to its automatic and adaptive capabilities for complex configurations.This paper revisited a classic Delaunay mesh generation algorithm,where a robust Bowyer-Watson incremental point insertion kernel is integrated.A complete scheme for conformal boundary and constrained boundary recovery is presented.Mesh quality is enhanced using both smoothing and topological techniques.Numerical experiments demonstrate that our algorithm is robust and reliable,and can produce high-quality computational meshes for complex aerodynamic configurations.
