Sažetak
Viscoelastic fluids are of great importance in many industrial sectors, such as in food and synthetic polymers industries. The rheological response of viscoelastic fluids is quite complex, including combination of viscous and elastic effects and highly non- linear viscous and elastic phenomena. This work presents a new Computational Fluid Dynamics (CFD) tool for the simulation of viscoelastic fluid flows, which consists of a viscoelastic fluid module to be used with OpenFOAM CFD package. The main reasons for using OpenFOAM in the development of this tool are its characteristics with relation to flexibility to deal with complex geometries, unstructured and non orthogonal meshes, moving meshes, large variety of interpolation schemes and solvers for the linear discretized system, and the possibility of data processing parallelization. Several constitutive equations, such as Maxwell, UCM, Oldroyd-B, Giesekus, Phan-Thien- Tanner (PTT), Finitely Extensible Nonlinear Elastic (FENE-P and FENE-CR) and some derivations of Pom-Pom were implemented, in single and multimode form, and in this work the results are presented with the Giesekus model. The proposed methodology was validated by comparing its predictions with experimental and numerical data from the literature for the analysis of a planar 4:1 contraction flow.
