..., the influence of Al 2 O 3 nanoparticles on the Ionic Liquid (IL)-based cutting fluid is investigated. For performing it, six varying ILs (ammonium-based and immidazolium) were mixed with Al 2 O 3 nanoparticles, and their lubricating behavior (viscosity, wettability, and thermal) were measured. Viscosity...

... Abstract Pool boiling experiment with a platinum wire was performed in earth and micro gravity. Bare surface and fouling surface with scale of calcium carbonate was used. The wettability on the scale surface was higher than that on the bare surface. The critical heat flux (CHF) was measured...

... such as grooves and protrusions exist on all metal surfaces. However, distinct morphologies can be seen for different metals, with the most variable microstructures for the titanium alloy. Moreover, the surface wettability to the distilled water for all metal surfaces was examined with a contact angle measuring...

...NANO-SCALE WETTABILITY OF FREE-STANDING CAPPED CARBON NANOTUBE ARRAYS Miray Ouzounian and Travis Shihao Hu Department of Mechanical Engineering, California State University, Los Angeles, CA ABSTRACT Countless organisms in nature have adapted high-aspect- ratio micro-/nano- fibrillar arrays...

... The surface nanostructure determines the system wettability and thus has significant effects on the thin liquid film spreading and phase change heat transfer. A model based on the augmented Young-Laplace equation and kinetic theory was developed to describe the nanoscale roughness effects on the extended...

... of ratcheted micropillars as well as submicrometer ratchets integrated into micropillars. In addition, we will discuss optimization of the SU-8 imprinting process and the air gap compensation for photolithography of ratcheted SU-8 layers, which are essential for the fabrication. wettability...

... 26 05 2009 An experimental set-up is developed to investigate the effects of surface energy/surface wettability on characteristics of two-phase flow in microchannels. Two-phase (water and air) slug flow is established in entrance effect free microchannel test sections of various...

... 31 03 2008 The wettability of the system in capillary covers is an important element to increase the boiling heat transfer on the coverings. The sessile drop methodology allows the evaluation of either the surface energy of solids or the interfacial energy of liquids, and from both...
