Title:
Shape optimization of airfoils for drag minimization over a range of operating conditions 
Abstract:
A continuous adjoint formulation is used to determine an optimal airfoil shape which has the least drag coefficient between Re = 10, 000 and 20, 000. An approach derived from concepts of robust design is employed for this purpose. A finite element method based on streamline-upwind Petrov/Galerkin (SUPG) and pressure stabilized Petrov/Galerkin (PSPG) stabilizations is used to solve both the flow and adjoint equations. The airfoil is parametrized via a Non-Uniform Rational B-Splines (NUR...    »
