Particle Removal Mechanisms Under Substrate Acceleration

Abstract

Abstract Particle detachment due to substrate acceleration is studied. The magnitude of the critical acceleration required to remove a particle from a surface based on the theory of critical moment and sliding detachment is determined. The special cases of spherical and cylindrical particles are examined, and the role of particle geometry on adhesion and detachment is studied. For different adhesion models, the critical substrate acceleration for particle removal is evaluated. The theoretical predictions are compared with the available experimental data and discussed.
