  2. 1. Control Strategy for Energy Efficient Fluid Power Actuators : Utilizing Individual Metering

    Author : Björn Eriksson; Jan-Olov Palmberg; Jonas Larsson; Jochen Pohl; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid power; mode switch; energy efficient; independent metering; split spool; poppet; Fluid mechanics; Strömningsmekanik;

    Abstract : This thesis presents a solution enabling lower losses in hydraulic actuator systems. A mobile fluid power system often contains several different actuators supplied with a single load sensing pump. One of the main advantages is the need of only one system pump. This makes the fluid power system compact and cost-effective. READ MORE

  4. 2. Impact of Icing on Wind Turbines Aerodynamic

    Author : Narges Tabatabaei; Michel Cervantes; Barakos George N.; Luleå tekniska universitet; []
    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

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

    Author : Markus Nordlund; []
    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

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

    Author : Jan-Erik Ögren; Luleå tekniska universitet; []
    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

  7. 5. Fluid flow in wood fiber network

    Author : Patrik Pettersson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Cellulose material is processed to pulp suspensions and MDF boards in order to produce products such as papers, magazines, laminate floors or door skins. A critical stage of these processes is when the cellulose fiber networks are compressed to specific densities and when most of the fluid originally positioned between and inside the fibers is forced to leave the network.
