Abstract

Spreading of liquids on solid substrates is governed by mechanisms which induce contact line motion. Providing mechanical vibrations to the substrate is one such method which has proved effective in displacing the contact line. In the present work we experimentally explore the spreading characteristics of a liquid due to the substrate's modal vibrations, in the frequency range of around 10kHz. The subsequent findings are then employed to subject the liquid to simultaneous low frequency actuations (in the 100Hz range) and substrate modal vibrations to produce a larger and a more evenly distributed spread about the substrate's axis than that obtained with any of the two methods individually.
