Understanding and modeling of viscoelastic fluid flows is essential for several industrial applications. Simulations of internal viscoelastic flows as well as of viscoelastic free-surface flows are quite complex and it is necessary to utilize advanced material models. This work focuses on the study of the Corotational Maxwell constitutive model which is implemented in the viscoelasticInterFoam solver developed with the OpenFOAM computational fluid dynamics package. Simulations of viscoelastic secondary flows in a square channel are presented and validated with experimental results. This is followed by a viscoelastic free-surface flow application to simulate a process developed within the Polymer Engineering Center that uses a micro-capillary die for the production of micropellets.
