  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. 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

  5. 3. A study of hydroelastic fluid-structure interaction with application to immersed cantilevers

    Author : Johan Lorentzon; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Partitioned Fluid-Structure; Blocked Gauss-Seidel; Jacobian-free Newton-Krylov methods; Incompressible fluid; Finite Strain; Total Lagrangian; Arbitrary Lagrange Euler method; Vector acceleration;

    Abstract : This study presents an approach for partitioned fluid-structure interaction (FSI) applied to large structural deformations, where an incompressible turbulent solver is combined with a structural solver. The implementation is based upon two different open-source libraries by using MPI as a parallel communication protocol, the packages deal. READ MORE

  6. 4. 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.

  7. 5. Fluid Management in Haemodialysis : Studies on current practices and new methods

    Author : Jenny Stenberg; Hans Furuland; Magnus Lindberg; Eva Tiensuu Janson; Bernd Stegmayr; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Haemodialysis; Fluid management; Fluid overload; Bioimpedance spectroscopy; Dry weight; Brain natriuretic peptide; Decision aid; Medicinsk vetenskap; Medical Science;

    Abstract : Chronic fluid overload has been identified as an independent predictor of mortality in haemodialysis patients, and 30% remain fluid overloaded at dry weight. The use of bioimpedance spectroscopy (BIS) in fluid management may improve blood pressure control and cardiovascular status. READ MORE
