New entropy estimates for Oldroyd-B and related models

D. Hu, T. Lelièvre

Research output: Contribution to journalArticlepeer-review


This short note presents the derivation of a new a priori estimate for the Oldroyd-B model. Such an estimate may provide useful information when investigating the long-time behaviour of macro-macro models, and the stability of numerical schemes. We show how this estimate can be used as a guideline to derive new estimates for other macroscopic models, like the FENE-P model.
