Inertial migration

Inertial forces are commonly neglected in small Reynolds number flows. However, they can play a crucial role in the dynamics of objects in microfluidics devices, even though Reynolds number is small

In particular, forces in the transverse direction of the movement may appear leading to different trajectories that depend on physical properties that can be exploited for sorting purposes. This phenomena is referred to as inertial migration.

In our work, we have studied the influence of inertial and surface tension forces on the equilibrium position of deformable bubbles.
