Abstract
In the present paper, the two-dimensional Navier-Stokes equations with the Giesekus constitutive equation are used to simulate a viscoelastic fluid flow in a straight channel. In added, as test cases Tollmien-Schlichting waves are introduced near the upstream boundary and propagated in the flow field. The simulation is done using a high-order compact finite difference scheme for the spatial derivatives discretization and with a parallelization method that makes a domain decomposition in both streamwise and normal flow direction. The present work investigates the efficiency of the parallelization method in the simulations that were made with different meshes, using different number of processing elements in both directions of the domain.
