Stokes layers in oscillatory flows of viscoelastic fluids: Viscoelastic layers in oscillatory flows

Abstract

Oscillatory flows of viscoelastic fluids are studied from the perspective of Stokes viscoelastic layers. We identify the governing dimensionless variables, and study the flows in a general way for fluids with linear rheology. Nonlinearities can be treated perturbatively to account for reported flow instabilities. This article is part of the theme issue 'Stokes at 200 (Part 1)'.
