Influence of rate of geometric dimensions to hydrodynamic resistance during the current of non newton medium in prismatic channels for the condition of equality of perimeters of cross section

The hydrodynamic structure of the flow of non Newtonian fluids in laminar flow in prismatic channel are investigated. For example, 0.65% fluid of Na CMC is taken. Influence of frictional factor resistance on the number Re for various geometrical dimensions of the samples at the same values of the perimeters are presented in this article. The distribution of viscosity and the second invariant of the rate of deformation tensor are presented. The numerical results presented here study and compare with results for a circular tube and the experimental data for flow of 0.65% fluid of Na CMC in a circular tube. In this work are received, that the frictional factor resistance increases with increasing ratio of the channel width to height.
