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.

The liquid flow around the vapor bubble is considered as an irrotational flow and then the flow around the vapor bubble is a potential flow.
BEM is based on "Green theory." Green theory states that every incompressible and irrotational flow can be simulated by source, dipole, or vortex distribution on its boundary surfaces .
Accordingly, greater hydrodynamic stresses are generated in elongational flow and stresses are transferred more efficiently to the agglomerates because rotational motion is absent in pure elongational flow (irrotational flow); as a consequence, the energy consumption is expected to be less in elongational flow relative to shear flow , This is why, in the present work, a new mixer design with predominantly elongational flow contribution (RMX) has been used as a different approach to obtain polymer/graphite nanocomposites.
Irrotational Flow and Real Fluid Effect under Planer Sluice Gate.
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.
In this work, we study the problem of HGMS of weakly magnetic particle using a microferromagnetic wire as capture center in irrotational flow of inviscid fluid.
In the case of one-dimensional approach, the continuity equation gives the velocity of product combustion in the form U = 2Xw/[R.sub.k], which coincides with the velocity of the irrotational flow field for two-dimensional case.
For an irrotational flow Where is the velocity of the fluid at any point of the flow field and is the total velocity potential.
The latter, p + [rho]gz + (1/2)[rho][v.sup.2] = constant, is associated with irrotational flow in (nearly) inviscid fluids (Chorin and Marsden 1993).
"The small residual effect is due to the special property of a superfluid and supersolid known as the irrotational flow effect.
