Pulsatile flow in curved pipes
TL;DR: In this article, the characteristics of some flows that occur when fluid is driven through a curved tube are disclosed for an imposed pressure gradient of pulsatile nature, varying sinusoidally with time about a non-zero mean.

Fluid Flow through 90 Degree Bends
TL;DR: In this paper, the authors present a review of pressure drop measurement and prediction in curved pipes and elbow bends for both laminar and turbulent single-phase fluid flow, showing that the pressure loss can be predicted both theoretically and using empirical relations.

Laminar secondary flows in curved rectangular ducts
Sivagnanam Thangam,Nahmkeon Hur +1 more
TL;DR: In this paper, the secondary flow of an incompressible viscous fluid in a curved duct is studied by using a finite-volume method, and it is shown that as the Dean number is increased, secondary flow structure evolves into a double vortex pair for low-aspect-ratio ducts and roll cells for ducts of high aspect ratio.

Note on the motion of fluid in a curved pipe
W. R. Dean,J. M. Hurst +1 more
TL;DR: In this paper, it is assumed that the actual secondary motion is replaced by a uniform stream; conditions in the central part of the section mainly determines the motion and the appropriate velocity of the stream can be determined from the relation that has been found experimentally between the rate of flow in a curved pipe and the pressure gradient.
