Purely-elastic flow instabilities in a microfluidic cross-slot geometry
In this work we demonstrate numerically, using a 3D finite-volume method, that viscoelastic flow in a microfluidic cross-slot geometry can lead to flow asymmetries under perfectly symmetric flow conditions. This supercritical instability is predicted using the upper-convected Maxwell model under cre...
