Regarding the interfacial defects of coextrusion, a large number of literatures have come up reporting on the theoretical and experimental advances and the underlying origins from both mechanical and numerical approaches |1], Yih  was the first who conducted a systematic numerical study on the stability of plane Poiseuille
flow of two Newtonian fluids considered within a framework of linear stability theory and he pointed out that the viscosity difference can cause instability regardless of the Reynolds number.
As a matter of fact, it has been found that this law allows describing not only the concentration gradient driven mass transport but also other important laws of physics: for instance Ohm's electric conductivity or Fourier's heat conductivity or Poiseuille
pressure laws .
No transition has yet occurred in the fully developed Poiseuille
region under small to medium amplitude disturbances.
In the present experiments, the Rayleigh number never exceeded 1160, thus Poiseuille
flow prevailed throughout the plain channel.
This rests upon the Poiseuille
equation, which demonstrates that resistance to flow of gas through a tube is directly proportional to length, while being inversely proportional to the radius of the tube to the fourth power (when flow is laminar).
Observation of aspherical particle rotation in poiseuille
flow via the resistance pulse technique.
flow of couple stress fluid has been critically examined by Chaturani and Rathod .
where r and the velocity components are scaled by the pipe radius R and the centerline streamwise velocity of thee laminar Poiseuille
profile Up respectively.
We studied the pressure driven, steady-state flow of an incompressible fluid through a straight channel, the Poiseuille

The 'Burdine' model (Burdine 1953) uses [beta] = 2, p = 2, q = 1, and is derived from the Poiseuille
equation and the capillary-rise equation.
was trying to understand blood flow but blood was too complicated so he started out his experiments just with water.
