WitrynaThe simulation of the 2D flow around NACA 0012 airfoil was carried out at Re= 6000000 R e = 6000000 (based on chord c = 1m c = 1 m ). The speed of sound was evaluated … Witryna11 kwi 2024 · It was found that up to 10° angle of attack, the standard NACA0012 profile shows a higher lift-to-drag, whereas at 15° and 20° angle of attack, as the penguin wing one is 122% and 60.62% higher than the NACA0012 aerofoil. Implementation of scaling the geometric features of penguins for wing design applications is also simulated and … WitrynaBy doing so, some differences in the static stall angle and the extent of the hysteresis cycle are discussed.
