Drop Spray Electrification
Riko Kazama, Masaya Toda, Hans-Jürgen Butt +1
Charge separation during the breakup of water drop has been recognized since the early studies of waterfall and spray electrification, yet the role of controlled drop fragmentation…
How Spontaneous Electrowetting and Surface Charge affect Drop Motion
Chirag Hinduja, Benjamin Leibauer, Rishi Chaurasia +5
Water drops sliding on hydrophobic surfaces spontaneously separate charges at their rear. It is unclear how this charge separation affects the contact angles of a sliding drop. We…
Stood-up drop to measure receding contact angles
Diego Díaz, Aman Bhargava, Franziska Walz +9
The wetting behavior of drops on natural and industrial surfaces is determined by the advancing and receding contact angles. They are commonly measured by the sessile drop techniqu…
Experimental Study of Condensation of Water on Polydimethylsiloxane-Coated Copper Surfaces
Till Pfeiffer, Shuai Li, Michael Kappl +3
Modification of surfaces to enable dropwise condensation is a promising approach for achieving high condensation rates. In this work, we present an experimental study on condensati…
Flow profiles near receding three--phase contact lines: Influence of surfactants
Benedikt B. Straub, Henrik Schmidt, Peyman Rostami +5
The dynamics of wetting and dewetting is largely determined by the velocity field near the contact lines. For water drops it has been observed that adding surfactant decreases the…
