Self-propulsion of Leidenfrost Drops between Non-Parallel Structures
(Springer NatureDepartment of Mechanical and Aerospace Engineering, The University of Texas at Arlington, 20 Septemb)In this work, we explored self-propulsion of a Leidenfrost drop between non-parallel structures. A theoretical model was first developed to determine conditions for liquid drops to start moving away from the corner of two ... -
Conditions for Barrel and Clam-Shell Liquid Drops to Move on Bio-inspired Conical Wires
(Springer NatureDepartment of Mechanical and Aerospace Engineering, The University of Texas at Arlington, August 29,)It has been reported that, in a foggy environment, water drops with either barrel or clam-shell shapes are capable of self-running on conical wire-like structures, such as cactus spines, spider silk, and water striders’ ... -
