| A Multidisciplinary Design Optimization code was developed for NASA Stator 37. 3 different RANS solvers, Spalart-Allmaras, K-epsilon, and K-o, were compared to design data to determine which was the fastest without significant error. K-o was shown to be the most accurate, while only being 13.3% slower than Spalart-Allmaras and 17% faster than K-epsilon. Variable stator blades were added to an optimized blade geometry and compared to a design case where the stator blade angle was a part of the design vector. The optimized blade without variable stator blades was able to reduce total pressure loss to be 66.5% of the starting point, while adding in variable stator blades only reduced total pressure loss to 77.5% of the starting point. |
