  1. 1. Capillary driven devices for patient-centric diagnostics

    Författare :Gabriel Lenk; Niclas Roxhed; Göran Stemme; Jens Ducrée; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Capillary driven; Microfluidic; Dissolvable valves; PVA; Volume metering; Dried Blood Spots; DBS; Dried Plasma Spots; DPS; Medicinsk teknologi; Medical Technology;

    Sammanfattning : Lateral flow assays is an example of a successful microfluidic platform relying on passive fluid transport, making them suitable for patient-centric and point-of-care applications. Flow control and valving in capillary driven devices typically rely on design-imprinted functions and operations which can be a limiting factor. LÄS MER

  3. 2. Diffuse-Interface Simulations of Capillary Phenomena

    Författare :Walter Villanueva; Gustav Amberg; Steffen Hardt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capillary-driven flows; wetting; Cahn-Hilliard Navier-Stokes system; multicomponent and multiphase flows; parallel adaptive computing; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : Fluid flows mainly driven by capillary forces are presented in this thesis. By means of modeling and simulations, interesting dynamics in capillary-driven flows are revealed such as coalescences, breakups, precursor films, flow instabilities, rapid spreading, rigid body motions, and reactive wetting.

  4. 3. Surface tension-driven flow in soft porous materials — An investigation of the mechanism of capillary flow in microchannels of hydrogels

    Författare :Johanna Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wetting on soft materials; Capillary flow; alginate gel; capillary action;

    Sammanfattning : Spontaneous spreading of liquids in porous materials is of great industrial relevance and occurs in, for example, diapers, fabrics, paper or paint. Often, it is necessary to manipulate the spreading rate of liquids to result in the desired mass transport, for example to soak up large liquid volumes, as in a diaper. LÄS MER
