| Abstract | Steady and unsteady compressible rotor airfoil aerodynamic calculations are made with an automated adaptive finite element method. The finite element flow solver is based on the time-discontinuous Galerkin least squares method. This type of finite element method is particularly suitable to handle problems with multiple relative motion. In addition to the flow solver, the automated adaptive environment utilized for these calculations is comprised of the Finite Quadtree mesh generator, and interpolation based error indicator, and a mesh enrichment procedure which is edge based and stores no mesh enrichment history. A brief description of this automated adaptive environment is also given. Correlation with experimental as well as other numerical data shows that this adaptive methodology is able to accurately calculate steady and unsteady compressible rotor airfoil flows. |
