Lift and Drag Coefficient Map of NACA4415 Airfoil
Journal of Physics: Conference Series, 2021 AbstractThe NACA4415 airfoil was numerically simulated with the help of the Fluent software to analyze its aerodynamic characteristics. Results are acquired as follows: The calculation accuracy of Fluent software is much higher than that of XFOIL software; the calculation result of SSTk-ω(sstkw) turbulence model is closest to the experimental value ...
