  2. Kutta–Joukowski theorem - Wikipedia

    en.wikipedia.org/wiki/KuttaJoukowski_theorem

    Kutta–Joukowski theorem is an inviscid theory, but it is a good approximation for real viscous flow in typical aerodynamic applications. [2] Kutta–Joukowski theorem relates lift to circulation much like the Magnus effect relates side force (called Magnus force) to rotation. [3] However, the circulation here is not induced by rotation of the ...

  3. Circulation (physics) - Wikipedia

    en.wikipedia.org/wiki/Circulation_(physics)

    This is known as the Kutta–Joukowski theorem. [6] This equation applies around airfoils, where the circulation is generated by airfoil action; and around spinning objects experiencing the Magnus effect where the circulation is induced mechanically. In airfoil action, the magnitude of the circulation is determined by the Kutta condition. [6]

  4. Lift (force) - Wikipedia

    en.wikipedia.org/wiki/Lift_(force)

    A solution of the potential equation directly determines only the velocity field. The pressure field is deduced from the velocity field through Bernoulli's equation. Comparison of a non-lifting flow pattern around an airfoil; and a lifting flow pattern consistent with the Kutta condition in which the flow leaves the trailing edge smoothly

  5. Lifting-line theory - Wikipedia

    en.wikipedia.org/wiki/Lifting-line_theory

    Lifting line theory supposes wings that are long and thin with negligible fuselage, akin to a thin bar (the eponymous "lifting line") of span 2s driven through the fluid. . From the Kutta–Joukowski theorem, the lift L(y) on a 2-dimensional segment of the wing at distance y from the fuselage is proportional to the circulation Γ(y) about the bar a

  6. Magnus effect - Wikipedia

    en.wikipedia.org/wiki/Magnus_effect

    The force on a rotating cylinder is an example of Kutta–Joukowski lift, [2] named after Martin Kutta and Nikolay Zhukovsky (or Joukowski), mathematicians who contributed to the knowledge of how lift is generated in a fluid flow. [3]

  7. Nikolay Zhukovsky (scientist) - Wikipedia

    en.wikipedia.org/wiki/Nikolay_Zhukovsky_(scientist)

    Nikolay Yegorovich Zhukovsky [1] (Russian: Никола́й Его́рович Жуко́вский, IPA: [ʐʊˈkofskʲɪj]; 17 January [O.S. 5 January] 1847 – 17 March 1921) was a Russian scientist, mathematician and engineer, and a founding father of modern aero-and hydrodynamics.

  8. Kutta condition - Wikipedia

    en.wikipedia.org/wiki/Kutta_condition

    When an airfoil is moving with an angle of attack, the starting vortex has been cast off and the Kutta condition has become established, there is a finite circulation of the air around the airfoil. The airfoil is generating lift, and the magnitude of the lift is given by the Kutta–Joukowski theorem. [5]: § 4.5

  9. Martin Kutta - Wikipedia

    en.wikipedia.org/wiki/Martin_Kutta

    Martin Wilhelm Kutta (German:; 3 November 1867 – 25 December 1944) was a German mathematician. In 1901, he co-developed the Runge–Kutta method, used to solve ordinary differential equations numerically. He is also remembered for the Zhukovsky–Kutta aerofoil, the Kutta–Zhukovsky theorem and the Kutta condition in aerodynamics.
