Web21 Jun 2024 · Large-eddy simulations (LESs) of low-Reynolds-number flow over a NACA0018 airfoil are performed to investigate flow control at the stall angle of attack (15 deg) by low-amplitude surface waves (actuations) of different types (backward/forward traveling and standing waves) on the airfoil’s suction side. It is found that the backward … Web2 Aug 2024 · Thick airfoils have previously been shown to stall gradually from the trailing edge, while thin airfoils tend to stall abruptly from the leading edge (Gault 1957; Loftin and Bursnall 1948). In the data presented here, the stall type is shown to vary with Reynolds number, depending on the relative locations of the hypothetical turbulent and laminar …

WebThis is true for most cases, because thin airfoils normally produce less drag and less lift than thick ones at the same angle of attack. But they are also exceptions. Thick airfoils, to be specific Supercritical airfoil, are commonly used by commercial airliners, but not only because they could produce less drag. http://airfoiltools.com/airfoil/naca4digit?MNaca4DigitForm%5Bcamber%5D=0&MNaca4DigitForm%5Bposition%5D=0&MNaca4DigitForm%5Bthick%5D=14&MNaca4DigitForm%5BnumPoints%5D=81&MNaca4DigitForm%5BcosSpace%5D=0&MNaca4DigitForm%5BcosSpace%5D=1&MNaca4DigitForm%5BcloseTe%5D=0
