Journal ArticleDOI
Design of ice-free nanostructured surfaces based on repulsion of impacting water droplets.
Lidiya Mishchenko,Benjamin Hatton,Vaibhav Bahadur,J. Ashley Taylor,Tom Krupenkin,Joanna Aizenberg +5 more
TL;DR: Factors contributing to droplet retraction, pinning and freezing are addressed by combining classical nucleation theory with heat transfer and wetting dynamics, forming the foundation for the development of rationally designed ice-preventive materials.
Journal ArticleDOI
Dynamics of Ice Nucleation on Water Repellent Surfaces
Azar Alizadeh,Masako Yamada,Ri Li,Wen Shang,Shourya Prakash Otta,Sheng Zhong,Liehui Ge,Ali Dhinojwala,Ken R. Conway,Vaibhav Bahadur,A. Joseph Vinciquerra,Brian Stephens,Margaret Louise Blohm +12 more
TL;DR: An in-depth analysis of ice formation dynamics upon water droplet impact on surfaces with different wettabilities is presented, finding that ice nucleation delay on superhydrophobic surfaces is more prominent at moderate degrees of supercooling, while closer to the homogeneous nucleation temperature, bulk and air-water interface nucleation effects become equally important.
Journal ArticleDOI
Predictive Model for Ice Formation on Superhydrophobic Surfaces
Vaibhav Bahadur,Lidiya Mishchenko,Benjamin Hatton,J. Ashley Taylor,Joanna Aizenberg,Tom Krupenkin +5 more
TL;DR: The framework of the present work is the first detailed modeling tool developed for the design and analysis of surfaces for various ice prevention/reduction strategies and can be used to study the influence of surface morphology, surface chemistry, and fluid and thermal properties on dynamic ice formation and identify parameters critical to achieving icephobic surfaces.
Journal ArticleDOI
An energy-based model for electrowetting-induced droplet actuation
TL;DR: In this article, an analytical model is developed to estimate the actuation force on a droplet moving between two electrodes, and the effects of dielectric parameters, electrode layout, droplet geometry and shape are discussed with the objective of maximizing the actuuation force.
Journal ArticleDOI
Electrowetting-Based Control of Static Droplet States on Rough Surfaces
TL;DR: The results obtained show that EW is a powerful tool to alter the relative stabilities of the Cassie and Wenzel states and enable dynamic control of droplet morphology on rough surfaces.
