Impact forces of water drops falling on superhydrophobic surfaces
Bin Zhang, Vatsal Sanjay, Songlin Shi +4
A falling liquid drop, after impact on a rigid substrate, deforms and spreads, owing to the normal reaction force. Subsequently, if the substrate is non-wetting, the drop retracts…
Wetting of an annular liquid in a capillary tube
Cunjing Lv, Steffen Hardt
In this paper, we systematically investigate the wetting behavior of a liquid ring in a cylindrical capillary tube. We obtain analytical solutions of the axisymmetric Young-Laplace…
Drop Impact on Two-Tier Monostable Superrepellent Surfaces
Songlin Shi, Cunjing Lv, Quanshui Zheng
Superrepellency is a favorable non-wetting situation featured by a dramatically reduced solid/liquid contact region with extremely low adhesion. However, drop impact often brings o…
Wetting States of Two-Dimensional Drops under Gravity
Cunjing Lv
An analytical model is proposed for the Young-Laplace equation of two-dimensional (2D) drops under gravity. Inspired by the pioneering work of Landau & Lifshitz (1987), we derive a…
Condensation and jumping relay of droplets on lotus leaf
Cunjing Lv, Pengfei Hao, Zhaohui Yao +3
Dynamic behavior of micro water droplet condensed on a lotus leaf with two-tier roughness is studied. Under laboratory environment, the contact angle of the micro droplet on single…
Driving Droplet by Scale Effect on Microstructured Hydrophobic Surfaces
Cunjing Lv, Pengfei Hao
A new type of water droplet transportation on microstructured hydrophobic surface is proposed and investigated experimentally and theoretically - water droplet could be driven by s…
