In this work, we carry out a numerical analysis of visco-elastic flow for the multi-mode Giesekus model under high shear rate flow. In the previous work, we proposed a new numerical scheme that is suited for the analysis of visco-elastic fluids. This scheme employs the MUSCL (Monotone Upstream-centered Scheme Conservation for Law)-TVD (Total Variation Diminishing) and the GSMAC (Generalized Simplified Maker and Cell)-FEM (Finite Element Method) for the numerical analysis of the constitutive equation and the momentum equation, respectively. Hence, we analyze the flow through the contraction plane for the multi-mode Giesekus model using this scheme. In this analysis, eight relaxation modes are considered. The results of this analysis are good agreement with the experimental data under low shear rate flow and the results are stable under high shear rate flow.
