  1. 1. Particle image velocimetry in practice

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Torbjörn Green; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering mechanics - Fluid mechanics; Teknisk mekanik - Strömningsmekanik; Strömningslära; Fluid Mechanics;

    Abstract : Experimental fluid mechanics has for a long time been used to visualize flow phenomenon. An early pioneer was Ludwig Prandtl who used aluminum particles in water flumes to describe the flow in a qualitative manner. In line with the rapid development of Computational Fluid Dynamics, CFD, the need for new validation tools has increased. READ MORE

  2. 2. Thirst in Patients with Heart Failure Description of thirst dimensions and associated factors with thirst

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Nana Waldréus; Tiny Jaarsma; Robert Hahn; Anna Forsberg; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart failure; thirst; fluid restriction; thirst intensity; thirst distress; thirst frequency; thirst quality; dehydration; symptom management;

    Abstract : Introduction: Nurses and other health care professionals meet patients with heart failure (HF) who report they are thirsty. Thirst is described by the patients as a concern, and it is distressing. READ MORE

  3. 3. A numerical study of two-fluid models for dispersed two-phase flow

    University dissertation from Stockholm : KTH

    Author : Reynir Levi Gudmundsson; Björn Sjögreen; Anders Petersson; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Numerical analysis; two-phase flow; two-fluid mode; well-posedness; numerical experiments; Numerisk analys; MATHEMATICS Applied mathematics Numerical analysis; MATEMATIK Tillämpad matematik Numerisk analys;

    Abstract : In this thesis the two-fluid (Eulerian/Eulerian) formulation for dispersed two-phase flow is considered. Closure laws are needed for this type of models. We investigate both empirically based relations, which we refer to as a nongranular model, and relations obtained from kinetic theory of dense gases, which we refer to as a granular model. READ MORE

  4. 4. Investigation of Rear-Mounted Cooling Module Installations for Heavy Vehicles

    University dissertation from Stockholm : KTH

    Author : Lisa Larsson; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooling package; Aerodynamics; Heat transfer; CFD;

    Abstract : Due to stricter emissions legislations and increasing fuel prices vehicle efficiency must be improved. A trend that has been seen during recent years is increased engine power for many vehicle segments. Different exhaust gas after-treatment systems have also been introduced to be able to meet the emission demands. READ MORE

  5. 5. Vehicle Disc Brake Roughness Noise Experimental Study of the Interior Noise andVibro-Acoustic Modelling of Suspension Systems

    University dissertation from Stockholm : KTH

    Author : Eskil Lindberg; Nils-Erik Hörlin; Peter Göransson; Wolfgang Kropp; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustics; disc brake; surface topography; wire brush noise; roughness noise; component mode synthesis; vehicle suspension;

    Abstract : Prediction of vehicle disc brake roughness noise is a non-trivial challenge. In fact, neither the source mechanisms, nor the transfer paths are so far well understood. READ MORE
