A scaling relationship between power and shear for Bernoulli pads at equilibrium

Bernoulli pads can create a significant normal force on an object without contact. The radial outflow which creates this also imposes shear the object. Better understanding improve pad designs in order to mitigate material deformation and damage, or allow be used as shear-based cleaning implements. Here, we use computational fluid dynamics explore parameter space show power-law relationship between power at inlet maximum stress. These simulations are validated by particle tracking velocimetry experiment. A stress Reynolds number is provided, some implications of observed scaling relationships explored.
