  2. 1. Modelling of Moving Contact Lines in Two-Phase Flows

    Author : Hanna Holmgren; Gunilla Kreiss; Stefan Turek; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational fluid dynamics; Two-phase flow; Contact lines; Scientific Computing; Beräkningsvetenskap;

    Abstract : Moving contact line problems appear in many natural and industrial processes. A contact line is formed where the interface between two immiscible fluids meets a solid wall. Examples from everyday life include raindrops falling on a window and water bugs resting on water surfaces. READ MORE

  4. 2. Towards accurate modeling of moving contact lines

    Author : Hanna Holmgren; Gunilla Kreiss; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : The present thesis treats the numerical simulation of immiscible incompressible two-phase flows with moving contact lines. The conventional Navier–Stokes equations combined with a no-slip boundary condition leads to a non-integrable stress singularity at the contact line. READ MORE

  5. 3. Molecular Processes in Dynamic Wetting : Du som saknar dator/datorvana kan kontakta Cathrine Bergh, [email protected] för information

    Author : Petter Johansson; Berk Hess; Erik Lindahl; Guillaume Galliero; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; contact lines; nanodroplets; computational physics; molecular dynamics; fluid dynamics; multi-phase flows; electrowetting; Biologisk fysik; Biological Physics;

    Abstract : The spreading of liquids onto and over surfaces is a fundamental process in nature. It is present in all forms and sizes: From rivers carving through landscapes, to our blood stream transporting nutrients to cells, and even single water molecules moving through channels into these cells.

  6. 4. Innovative Contact Free Sensors for Metallurgical Process Control

    Author : Donald Malmberg; Stuart M. Millman; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; microwave spectroscopy; laser; TDLAS; high temperature; gas; slag; NATURAL SCIENCES; NATURVETENSKAP; spectroscopy; slag analysis; high temperatures; Mät- och instrumenteringsteknik; Instrumentation technology; TDLAS; microwave; laser; Fysicumarkivet A:2003:Malmberg;

    Abstract : The steel- and metal industry has an extensive production processing comprising many different process steps of solid, gaseous and liquid nature. Thus it is obvious that a number of different measurement technologies must be used to collect and evaluate key physical parameters which are necessary to control the production processes. READ MORE

  7. 5. Fabrication, characterization, and modeling of metallic source/drain MOSFETs

    Author : Valur Gudmundsson; Per-Erik Hellström; Yee-Chia Yeo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallic source drain; contact resistivity; Monte Carlo; NiSi; PtSi; SOI; UTB; tri-gate; FinFET; multiple-gate; nanowire; MOSFET; CMOS; Schottky barrier; silicide; SALICIDE;

    Abstract : As scaling of CMOS technology continues, the control of parasitic source/drain (S/D) resistance (RSD) is becoming increasingly challenging. In order to control RSD, metallic source/drain MOSFETs have attracted significant attention, due to their low resistivity, abrupt junction and low temperature processing (≤700 °C). READ MORE
