Numerical study of viscoelastic flow between eccentrically rotating cylinders

FENE-P fluid flow between eccentric rotating cylinders is simulated by using an unstructured finite volume method which has second-order accuracy in space. Effects of angular speeds of inner and outer cylinders, viscoelasticity and eccentricity ratio on the flow have been explored by varying different parameters or different computational zones. Results indicate that rotation boundary condition is a significant factor to both streamline pattern and stress pattern. Deborah number and eccentricity ratio have great effect on stress. Present Results are hoping to be more helpful in industry application.
