Figure 1: A variant of classical viscous fingering. The control of interfacial instabilities is similarly applicable in expanding narrow passages. For instance, our results suggest that when a less ...

Viscous fingering occurs when a thinner fluid pushes a thicker, more viscous fluid in a porous medium, like underground rock, ...

We present a three-dimensional model of flow driven by pumping without valves (valveless pumping) in a closed loop system in which the closed loop of tubing is immersed in an incompressible viscous ...
