It is necessary to correct data of supercritical airfoil for sidewall boundary-layer effects in transonic wind tunnel, thus investigating the aerodynamic characteristics of supercritical airfoil perfectly. In this paper, NASA SC (2)-0714 airfoil was numerically simulated with chosen grids, and compared with corrected EFD results. The Barnwell-Sewell(B-S)(More)
In order to boost the convergence speed of Genetic algorithms (GAs), some amelioration was made on the standard Genetic algorithm, a new crossover and a new mutation were designed in this paper. According to the numerical tests, the convergence speed of ameliorated Genetic algorithms accelerated apparently. In the Rae2822 supercritical airfoil drag(More)
The Reynolds number influences on aerodynamics of a typical supercritical airfoil were analyzed in this paper. The simulation of Reynolds number was achieved through wind tunnel test and numerical method. The maximum experimental Reynolds number reached 10 million per airfoil chord, while the numerical simulation could reach 50 million per airfoil chord(More)
