Experimental evidence for a short-wave global mode in film flow along periodic corrugations
(2013)The primary instability of liquid film flow along periodically corrugated substrates is studied experimentally. Two different wall shapes, of the same wavelength and height, are tested for a wide range of inclinations. It ... -
Experimental study of inclined film flow along periodic corrugations: The effect of wall steepness
(2006)Gravity-driven film flow along an inclined periodic wall with transverse rectangular corrugations is studied experimentally. The effect of corrugation steepness (=height/length) is considered in detail and an interesting ... -
Fabrication of super-hydrophobic surfaces for enhanced stone protection
(2009)In the current study, we demonstrate that the modification of a commercial siloxane protective composition by the addition of silica nanoparticles substantially enhances its protective efficiency and renders the treated ... -
Linear resonance in viscous films on inclined wavy planes
(2008)We study viscous gravity-driven films flowing over periodically undulated substrates. Linear analysis describes steady flow along small amplitude corrugations for films of arbitrary thickness. Solving the resulting system ... -
Nonlinear resonance in viscous films on inclined wavy planes
(2009)We study nonlinear resonance in viscous gravity-driven films flowing over undulated substrates. Numerical solution of the full, steady Navier-Stokes equations is used to follow the emergence of the first few free-surface ... -
Steady solutions of inertial film flow along strongly undulated substrates
(2011)Steady flow of a liquid film along sinusoidal, steeply corrugated walls is investigated by finite-element simulation of the 2D Navier-Stokes equations. Resonance between the wall and capillary-gravity waves travelling ... -
Superhydrophobic composite films produced on various substrates
(2008)Hydrophilic silica NOD nanoparticles were dispersed in solutions of poly(methyl methacrylate) (PMMA) and in solutions of a commercial poly(alkyl siloxane) (Rhodorsil 224), and the suspensions were sprayed on glass surfaces. ... -
Superhydrophobic films for the protection of outdoor cultural heritage assets
(2009)A very simple method that can be used to impart superhydrophobicity to stone surfaces of monuments using common and low-cost materials that are already employed or are easy to be found by conservators is presented. A ... -
Yield prediction in apples using Fuzzy Cognitive Map learning approach
(2013)This work investigates the yield modeling and prediction process in apples (cv. Red Chief) using the dynamic influence graph of Fuzzy Cognitive Maps (FCMs). FCMs are ideal causal cognition tools for modeling and simulating ...
