| Abstract: | The aim of this paper is to analyze the unsteady
flow of a non-Newtonian incompressible second-order
fluid in a straight rigid axisymmetric tube with circular crosssection
of constant radius. To study this problem, we use
the 1D nine-director Cosserat theory approach which reduces
the exact three-dimensional equations to a system depending
only on time and on a single spatial variable. From this onedimensional
system we obtain the relationship between mean
pressure gradient and volume flow rate over a finite section of
the tube. Attention is focused on some numerical simulation
of steady/unsteady flows for specific mean pressure gradient
and on the analysis of perturbed flows. |
