Critical shear rate and torque stability condition for a particle resting on a surface in a fluid flow

We have built a cone-plane experimental apparatus which enables measurement of γ̇c over a wide range of particle Reynolds number Rep from 10−3 to 1.5 × 103. The condition to dislodge the particle is found to b...
