| dc.description.abstract | The aim of this paper is to analyze the perturbed flows of a non-Newtonian incompressible second-order fluid in a straight rigid axisymmetric tube with circular cross-section 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 one-dimensional 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 on the analysis of perturbed flows. | por |
