Abstract
This work deals with the application of the integral KBKZ-PSM constitutive equation to axisymmetric flow problems. The mass and momentum equations are solved by a finite difference technique presented by Tomé and co-workers. The Finger tensor is modeled by the deformation fields method proposed by Hulsen and co-workers while the integral KBKZ equations describing the components of the extra-stress tensor are solved by a second-order quadrature formula. The methodology employed is applied to simulate tube flows and is verified by using mesh refinement and an analytic solution for fully developed axisymmetric flow in a tube.
