Numerical Study of Shear and Extensional Inelastic Contraction Flows

This study investigates the numerical solution of viscous sharp contraction flow using a time-step Taylor-Galerkin-pressure correction finite element method (T-G/P-C). Such complex problfem displays start-up, 4:1contraction creeping flow, shear viscosity and extensional responses. Here, inelastic shear-extensional model is proposed with single power-index response identical in extension, namely Fit-I. In this context, extension rate are defined by depending on second third invariants deformation tensor. Employing (T-G/P-C) combining representation to treat such problem gives novel scenario. The interesting lies determining efficient effect relevant parameters solutions components, convergence issues. Attention also paid impact these issues
