  1. 1. Particle image velocimetry in practice

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Torbjörn Green; Luleå tekniska universitet.; [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; Linköpings universitet.; Linköpings universitet.; [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; KTH.; [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. On Gas Dynamics of Exhaust Valves

    University dissertation from KTH Royal Institute of Technology

    Author : Marcus Winroth; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Exhaust valve; poppet valve; dynamic valve; engine modeling; discharge coefficient; Avgasventil; rörlig ventil; motorsimulering; utsläppskoefficient; Teknisk mekanik; Engineering Mechanics;

    Abstract : With increasing effects of global warming, efforts are made to make transportationin general more fuel efficient. When it comes to internal combustion engines,the most common way to improve fuel efficiency is through ‘downsizing’. Downsizingmeans that a smaller engine (with lower losses and less weight) performsthe task of a larger engine. READ MORE

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

    University dissertation from KTH Royal Institute of Technology

    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
