  1. 1. Fluid flow through and deformation of wood fiber networks

    University dissertation from Luleå : Luleå tekniska universitet

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

    Abstract : Cellulose-based commercial items such as paper and laminated flooring are vital to the local economy of northern Sweden. These products are commonly manufactured in suspension where fluids such as water or air are drained through the fiber network in some value-added steps in the manufacturing process. READ MORE

  2. 2. Impact of Icing on Wind Turbines Aerodynamic

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Narges Tabatabaei; Michel Cervantes; Barakos George N.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Wind energy covered 11.6% of Europe electricity demand in 2017. Region with cold climates represent a strong potential for wind energy companies because of their sparse population and proper wind conditions. The global wind energy installations in cold climate regions is forecasted to reach a capacity of 186 GW by the end of 2020. READ MORE

  3. 3. Transients in high head Francis turbines

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Chiragkumar Trivedi; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Francis turbine; load variation; load rejection; start-stop; emergency shutdown; transient; runaway; computational fluid dynamics; runner; transients; blade; power grid; Engineering mechanics - Fluid mechanics; Teknisk mekanik - Strömningsmekanik; Strömningslära; Fluid Mechanics;

    Abstract : On demand energy market and favourable government policies to encourage the usage of renewable energy have led to a dramatic increase of grid connected wind, solar, and other power in recent years. Penetration of the power above manageable limit, produced using intermittent energy sources, to meet the demand has induced instable grid operations. READ MORE

  4. 4. Noise radiation from drill steels and other experimental investigations in acoustics and fluid mechanics

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Jan-Erik Ögren; [1983]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Drill rod noise has become a major noise source in percussive drilling. Generation of flexural waves, which seem to be responsible for most of the noise, is studied in a model with dynamic photoelasticity and in the real drill rod with strain gauge technique. READ MORE

  5. 5. Permeability of non-crimp fabrics : a computational fluid dynamics approach

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Markus Nordlund; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : In the present market for manufacturing of high performance structural parts for various applications such as aerospace, transportation, infrastructure, marine, sports and recreation, low weight, high performance composites are preferable. Non-Crimp Fabrics (NCFs) are often used for such applications due to its high mechanical properties and often cost effective production. READ MORE
