  3. 2. Rapid wetting - influence of surface geometry and fluid properties

    Författare :Susumu Yada; Fredrik Lundell; Shervin Bagheri; Minh Do-Quang; Gustav Amberg; Jacco Snoeijer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wetting; spreading; surface structures; droplet; contact line; two-phase flow; non-Newtonian flow; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Wetting of a liquid on a solid surface is ubiquitous in everyday life, such as morning dew on a plant leaf and raindrops hitting on a glass window. However, this phenomenon is far away from being completely understood. LÄS MER

  4. 3. Wetting and drying of aerogel-based coating mortars in Swedish climates

    Författare :Ali Naman Karim; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; runoff; Aerogel; retrofitting; coating mortar; wetting; drying; wind-driven rain; render;

    Sammanfattning : Aerogel-based coating mortars (ACMs) have emerged as energy-efficient wall finishes with thermal conductivities of 30–50 mW/(m∙K). These coating mortars represent a promising alternative to traditional thermal insulation materials for retrofitting uninsulated building envelopes particularly in culturally significant structures.

  5. 4. Atomic-scale modelling of interfaces in cemented carbides: wetting and strength

    Författare :Martin Gren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; adhesion; density functional theory; hardmetals; cemented carbides; WC-Co; surfaces; interfaces; grain boundaries; wetting; phase boundaries;

    Sammanfattning : Cemented carbides are composite materials of great technological and industrial importance. They have a unique combination of hardness and toughness and are therefore used widely as tool materials in applications where both high hardness and toughness are demanded. These applications include among others: mining, turning, cutting and milling. LÄS MER

  7. 5. Hydrophobic surfaces: Effect of surface structure on wetting and interaction forces

    Författare :Petra M Hansson; Per M. Claesson; Agne Swerin; Adam C Simonsen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydrophobic surface; superhydrophobic surface; atomic force microscopy; surface forces; capillary forces; cavitaion; surface roughness; friction; wetting; confocal Raman; contact angles; surface preparation; Langmuir-Blodgett;

    Sammanfattning : The use of hydrophobic surfaces is important for many processes both in nature and industry. Interactions between hydrophobic species play a key role in industrial applications such as water-cleaning procedures and pitch control during papermaking but they also give information on how to design surfaces like hydrophobic mineral pigments.
