Analysis and optimization of slotted airfoils for a stator cascade

After the definition of slotted airfoils and their main features, the first activity is the validation of CFD results using data from Pratt & Whitney's experiments for a statoric cascade of an axial compressor. After the validation, a parametrization of NACA 65 slotted airfoils is implemented to study the effects of slot location and geometry on performance. A genetic algorithm is used for the optimization of the slot, to find the best slots for some specific combinations of camber, stagger and turning angle. Finally, also the camberline has been unlocked, allowing a completely free parametrization of airfoil's shape and slot geometry. The same optimization problem has been implemented and a comparison of performance about slotted and unslotted optimized airfoils complete the work.
