I will discuss two problems where flow instability drives a complex fluid -- or at least its mathematical model -- into intrinsic oscillations and unsteadiness. Both are in the Stokesian regiime where inertial effects are negligible. In the first, a visco-elastic fluid described by the Oldroyd-B model is driven by a background force that creates...

Mixing is a key issue in microfluidics, including droplet-based "digital" microfluidics. In electrowetting, internal flow patterns inside drops can be generated without any lateral translation if the drops are excited with AC voltage. Two regimes can be distinguished: at AC frequencies of the order of the eigenfrequency (typically O(1kHz) or les...
