The Steady Slow Motion of a Viscous Fluid through a Tapered Tube
TLDR
In this article, the steady slow motion of an incompressible viscous fluid through a tapered tube is investigated, and the dependence of the distribution of shear stress on the semi-angle of the cone is examined theoretically.Abstract:
It is the purpose of this paper to investigate the steady slow motion of an incompressible viscous fluid through a tapered tube, and to examine theoretically the dependence of the distribution of shear stress on the semi-angle of the cone. The volume of flow per unit time has also been calculated and a formula corresponding to the Poiseuille's equation has been obtained. In our calculations it is assumed that the velocity of the liquid is so small that the inertia term in the Navier-Stokes equations of motion can be neglected.read more

TL;DR: In this paper, a simple formula for estimating pressure drop of polymeric materials in a converging die with an abrupt change in geometry for many polymer processes was derived based on a power-law fluid model with normal-stress effects incorporated.

TL;DR: The relationship between pressure drop and flow rate through conically tapered needles was experimentally quantified as a function of fluid viscosity and microneedle length, diameter, and cone half-angle as discussed by the authors.

The Steady Flow of a Viscous Fluid through a Conical Nozzle
TL;DR: In this article, the authors presented a theory of the steady flow of Newtonian liquid through a conical nozzle, where the velocity is given byvr=3A(cos2θ-cos2α)/4r2, where α is the semi-angle of the cone, and A is a constant.
