  1. 21. Extending MRI to the Quantification of Turbulence Intensity

    Author : Petter Dyverfeldt; Tino Ebbers; Krishna Nayak; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulence intensity; cardiovascular disease; blood flow; hemodynamics; magnetic resonance imaging; generalized phase-contrast MRI; turbulent flow; Medical technology; Medicinsk teknik; Fluid mechanics; Strömningsmekanik;

    Abstract : In cardiovascular medicine, the assessment of blood flow is fundamental to the understanding and detection of disease. Many pharmaceutical, interventional, and surgical treatments impact the flow. The primary purpose of the cardiovascular system is to drive, control and maintain blood flow to all parts of the body.

  2. 22. Numerical computations of wind turbine wakes

    Author : Stefan S. A. Ivanell; Dan Henningson; Peinke Joachim; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Actuator Line Model; Actuator Disc Model; Wind Turbine Wake; CFD; LES; EllipSys3D; Fluid mechanics; Strömningsmekanik;

    Abstract : Numerical simulations of the Navier-Stokes equations are performed to achieve a better understanding of the behaviour of wakes generated by wind turbines. The simulations are performed by combining the in-house developed computer code EllipSys3D with the actuator line and disc methodologies. READ MORE

  3. 23. Large Eddy Simulation of Impinging Jets

    Author : Thomas Hällqvist; Laszlo Fuchs; Pierre Sagaut; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Impinging jet; large eddy simulation; heat transfer; vortex formation; circular jet; forcing; inflow conditions; implicit modeling.; Fluid mechanics; Strömningsmekanik;

    Abstract : This thesis deals with Large Eddy Simulation (LES) of impinging air jets. The impinging jet configuration features heated circular jets impinging onto a flat plate. The problem addressed here is of generic nature, with applications in many engineering devices, such as cooling of components in gas turbines, in cars and electronic devices. READ MORE

  4. 24. Dynamics of Exhaust Valve Flows and Confined Bluff Body Vortex Shedding

    Author : Marcus Winroth; P. Henrik Alfredsson; Knud Erik Meyer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

    Abstract : This thesis can be divided into two interconnected topics; engine exhaust-valve flows and confined bluff-body vortex shedding. When optimising engine flow systems it is common to use low order simulation tools that require empirical inputs, for instance with respect to flow losses across the exhaust valves. READ MORE

  5. 25. Procedure for the reduction of the effect of transient whole body vibrations

    Author : Peter Jönsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Abstract : There is a growing interest in the topic areas of increased vibration comfort and reduced vibration levels in work vehicles. Legislation, health costs and demands for increased competitiveness are all important motivating factors in this growing interest. READ MORE
