Review of Fluid Slip over Superhydrophobic Surfaces and Its Dependence on the Contact Angle
TL;DR: In this paper, a review of hydrophobicity is presented, with the goal of investigating the relationship, if any, between the contact angle (a macroscopically observed property) and the slip length (a microscopic phenomenon).
Journal ArticleDOI
Liquid water can slip on a hydrophilic surface.
TL;DR: Simulation results demonstrate that hydrophilic surfaces can show features typically associated with hydrophobicity, namely liquid water slip, and this dichotomy might be purely coincidental.
Journal ArticleDOI
Scalable, eco-friendly and ultrafast solar steam generators based on one-step melamine-derived carbon sponges toward water purification
Feng Gong,Hao Li,Wenbin Wang,Jigang Huang,Dawei Xia,Dawei Xia,Jiaxuan Liao,Mengqiang Wu,Dimitrios V. Papavassiliou +8 more
TL;DR: In this paper, the authors demonstrate a facile, scalable and low-cost approach to produce highly-efficient solar steam generator via a one-step calcination of commercial melamine sponges (MS) in air.
Journal ArticleDOI
Boundary slip and wetting properties of interfaces: correlation of the contact angle with the slip length
TL;DR: It is demonstrated that fluid-solid interfaces with low epsilonr and high sigmar should be chosen to increase slip and are prime candidates for drag reduction.
Journal ArticleDOI
Transport of a passive scalar in a turbulent channel flow
TL;DR: In this article, the spatial variation of eddy conductivity for Pr = 1 is interpreted in terms of the time dependency of diffusion from single sources, and support is provided for experimental studies which show that the dimensionless mass transfer coefficient varies as Sc−0.704 at large Sc.
