| Abstract: | We consider a second-order viscous fluid with swirling motion flowing in a circular
straight tube with constant radius. Integrating the equation of conservation of linear
momentum over the tube cross section with the velocity field approximated by the
Cosserat theory, we obtain a one-dimensional system depending only on time and on
a single spatial variable. From this 1D model, we derive the relationship between
mean pressure gradient and volume flow rate over a finite section of the tube as well
the wall shear stress. |
