Since the C border of the cylinder is a streamline itself, the stream function does not change on it, and [math]\displaystyle{ d\psi = 0 \, }[/math]. It is named for German mathematician and aerodynamicist Martin Wilhelm Kutta. We also use third-party cookies that help us analyze and understand how you use this website. The KuttaJoukowski theorem is a fundamental theorem in aerodynamics used for the calculation of lift of an airfoil and any two-dimensional body including circular cylinders translating in a uniform fluid at a constant speed large enough so that the flow seen in the body-fixed frame is steady and unseparated. The Kutta - Joukowski formula is valid only under certain conditions on the flow field. Updated 31 Oct 2005. The velocity is tangent to the borderline C, so this means that [math]\displaystyle{ v = \pm |v| e^{i\phi}. is the stream function. The Kutta-Joukowski theorem is valid for a viscous flow over an airfoil, which is constrained by the Taylor-Sear condition that the net vorticity flux is zero at the trailing edge. on the other side. [6] Let this force per unit length (from now on referred to simply as force) be [math]\displaystyle{ \mathbf{F} }[/math]. The theorem applies to two-dimensional flow around a fixed airfoil (or any shape of infinite span).
