Vorticity — is a mathematical concept used in fluid dynamics. It can be related to the amount of circulation or rotation (or more strictly, the local angular rate of rotation) in a fluid.Clancy, L.J., Aerodynamics , Section 7.11] The average vorticity zeta… … Wikipedia
Crocco's Theorem — is a fluid dynamics theorem relating the velocity, vorticity, and stagnation pressure (or entropy) of a potential flow. The theorem was first written by Italian scientist Gaetano Crocco. Because stagnation pressure loss and entropy generation can … Wikipedia

Circulation (fluid dynamics) — In fluid dynamics, circulation is the line integral around a closed curve of the fluid velocity. Circulation is normally denoted . If is the fluid velocity on a small element of a defined curve, and is a vector representing the differential… … Wikipedia
Conservative vector field — In vector calculus a conservative vector field is a vector field which is the gradient of a function, known in this context as a scalar potential. Conservative vector fields have the property that the line integral from one point to another is… … Wikipedia
Raychaudhuri equation — In general relativity, Raychaudhuri s equation is a fundamental result describing the motion of nearby bits of matter.The equation is important as a fundamental lemma for the Penrose Hawking singularity theorems and for the study of exact… … Wikipedia
Helmholtz's theorems — In fluid mechanics, Helmholtz s theorems describe the three dimensional motion of fluid in the vicinity of vortex filaments. These theorems apply to inviscid flows and flows where the influence of viscous forces is small and can be… … Wikipedia
Kutta condition — The Kutta condition is a principle in steady flow fluid dynamics, especially aerodynamics, that is applicable to solid bodies which have sharp corners such as the trailing edges of airfoils. It is named for German mathematician and aerodynamicist … Wikipedia
