SELF-PROPULSION OF LIQUID DROPS BETWEEN NON-PARALLEL STRUCTURES AT LEIDENFROST STATE
Abstract
In this work, we explored self-propulsion of a liquid drop between non-parallel structures at a temperature above its Leidenfrost point. A theoretical model was first developed to determine conditions for a drop to move away from the corner of two non-parallel plates. Subsequently, these results were validated by experiments. Finally, in Leidenfrost states, both lyophilic and lyophobic drops were shown to have the same dimensional movements away from the corner of two non-parallel plates.
