New results in rotating Hagen–Poiseuille flow

Journal of Fluid Mechanics, 2000
New three-dimensional finite-amplitude travelling-wave solutions are found in rotating Hagen–Poiseuille flow (RHPF[Ωa, Ωp]) where fluid is driven by a constant pressure gradient along a pipe rotating axially at rate Ωa and at Ωp about a perpendicular diameter.

Hagen–Poiseuille Flow in Semi-Elliptic Microchannels

Journal of Fluids Engineering, Transactions of the ASME, 2012
In this paper, an exact solution of Hagen–Poiseuille flow in microchannels with semi-elliptic cross sections is obtained. The velocity, shear stress distribution, and the friction factor are calculated and compared to known approximate solutions in the literature.

Laminar-Turbulent Transition in Hagen–Poiseuille Flow of a Real Gas

Journal of Turbulence, 2016
ABSTRACTThe effect of gas non-ideality on the laminar-turbulent transition is studied experimentally as the flow in a long circular tube at room temperature. The gases SF6 and Ar, differing significantly in the value of the second virial coefficient, were chosen for this study. Experiments were carried out by varying the pressure at the tube inlet (the

Hagen-Poiseuille Flow in Tubes of Semi-Circular Cross-Sections

2011 Fourth International Conference on Modeling, Simulation and Applied Optimization, 2011
In this paper, an exact solution of Hagen-Poiseuille flow in channels of semi-circular cross-sections is obtained as no such available in the literature. The velocity profile across the cross section and the shear stress distribution along the wall of the channel are calculated.

A Paradox With the Hagen-Poiseuille Relation for Viscous Fluid Flow

American Journal of Physics, 2014
Viscous laminar fluid flow in a pipe is described by the well known Hagen-Poiseuille relation. According to this relation, the velocity of the fluid is directly proportional to the pressure difference between the ends of the pipe and the square of the radius of the pipe and inversely proportional to its length.
