High Reynolds number and high Weissenberg number Oldroyd-B model with dissipation

Abstract

We give a small data global well-posedness result for an incompressible Oldroyd-B model with wave number dissipation in the equation of stress tensor. The result is uniform in solvent Reynolds numbers, and requires only fractional wave-number dependent dissipation $(-\Delta {)}^{\beta }$, $\beta \ge \frac{1}{2}$ in the added stress.
