irrotational flow

irrotational flow

[¦ir·ə′tā·shən·əl ′flō]
(fluid mechanics)
Fluid flow in which the curl of the velocity function is zero everywhere, so that the circulation of the velocity about any closed curve vanishes. Also known as acyclic motion; irrotational motion.

Covering first irrotational flow motion of an ideal fluid, then the theory and applications of real fluid flows, he discusses such topics as ideal fluid flows and irrotational flow motion; basic equations and flow analogies for two-dimensional flows; Joukowski transformation, the theorem of Kutta-Jourkowski, and lift force on an airfoil; and turbulence, and applying boundary layer theory to laminar boundary layer flows.
