Hagen-Poiseuille Flow in a Quarter-Elliptic Tube
Fluids, 2023 We present a rare exact solution of the Navier–Stokes equations for the Hagen–Poiseuille flow through a quarter-elliptic tube. Utilizing the separation of variables method, we derive the solution and report expressions for both the volumetric flow rate ...

Effect of Hydrophobic Coating on Hagen-Poiseuille Flows
Journal of Applied Fluid Mechanics, 2016 The effect of a hydrophobic coating on the flow through circular pipes with Newtonian fluids has been investigated. Velocity fields inside a pipe were experimentally determined by the particle image velocimetry (PIV) technique. The test fluid presented a

Non-Modal Stability in Hagen-Poiseuille Flow of a Bingham Fluid [PDF]
Physics of Fluids, 2014 Linear stability in Hagen-Poiseuille flow of a Bingham fluid is considered. Bingham fluid exhibits a yield stress in addition to a plastic viscosity. A Bingham number B, which describes the ratio of yield and viscous stresses, is used to characterize the behavior of Bingham-Hagen-Poiseuille flow. The effects of B on the stability are investigated using

Mathematical Analysis of Poiseuille Flow of Casson Fluid past Porous Medium [PDF]
Journal of Applied and Computational Mechanics, 2022 In this article, the influence of microstructure in the Casson fluid flow through a porous medium is investigated, by extending the Buckingham-Reiner’s one-dimensional model to plane-Poiseuille flow and Hagen-Poiseuille flow geometries.

Theoretical Study on Poiseuille Flow of Herschel-Bulkley Fluid in Porous Media [PDF]
Journal of Applied and Computational Mechanics, 2022 This theoretical study analyses the effects of geometrical and fluid parameters on the flow metrics in the Hagen-Poiseuille and plane-Poiseuille flows of Herschel-Bulkley fluid through porous medium which is considered as (i) single pipe/single channel ...

Adaptive Hagen–Poiseuille flows on graphs
Physica D: Nonlinear Phenomena, 2022 We derive a class of equations describing low Reynolds number steady flows of incompressible and viscous fluids in networks made of straight channels, with several sources and sinks, and adaptive conductivities. The flow is controlled by the fluxes at sources and sinks.

Uniform Structural Stability of Hagen–Poiseuille Flows in a Pipe
Communications in Mathematical Physics, 2022 In this paper, we prove the uniform nonlinear structural stability of Hagen-Poiseuille flows with arbitrary large fluxes in the axisymmetric case. This uniform nonlinear structural stability is the first step to study Liouville type theorem for steady solution of Navier-Stokes system in a pipe, which may play an important role in proving the existence ...

Universal dynamics in the onset of a Hagen-Poiseuille flow [PDF]
Physical Review E, 2006 The dynamics in the onset of a Hagen-Poiseuille flow of an incompressible liquid in a channel of circular cross section is well-studied theoretically. We use an eigenfunction expansion in a Hilbert space formalism to generalize the results to channels of arbitrary cross section. We find that the steady state is reached after a characteristic time scale
