Gravitational spreading of granular paste droplets induced by mechanical vibrations

Author affiliations

Abstract

Spreading experiments of granular paste droplets over a smooth and hydrophilic plate under vertical vibrations were performed. We show that applying vibrations tunes the spreading by changing the apparent viscosity of the paste and makes a Newtonian regime appear where R(t) ∝ t1/8. In this regime, the influence of the intensity of the vibrations, the diameter of the particles and the interstitial viscosity is investigated, and all experiments are rationalized by a lubrication Peclet number, in agreement with previous results from the literature.
