Proximity effect on hydrodynamic interaction between a sphere and a plane measured by Force Feedback Microscopy at different frequencies

Simon Carpentier, Mario S. Rodrigues, Elisabeth Charlaix +1

In this article, we measure the viscous damping $G^{\prime \prime },$ and the associated stiffness $G^{\prime },$ of a liquid flow in sphere-plane geometry in a large frequency range. In this regime, the…
