  3. 2. Experimental studies of turbulent boundary layer separation and control

    Författare :Kristian Angele; KTH; []
    Nyckelord :turbulence; boundary layer; separition; adverse pressure graddient;

    Sammanfattning : The object ofthe present work is to experimentally study thecase ofa turbulent boundary layer subjected to an AdversePressure Gradient (APG) with separation and reattachment. Thisconstitutes a good test case for advanced turbulence modeling. LÄS MER

  4. 3. Development and simulated observations of the Jovian Neutrals Analyzer

    Författare :Angèle Pontoni; Manabu Shimoyama; Mats Holmström; Ove Andersson; Andrew Yau; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; space instrumentation; space physics; Ganymede; Jupiter; fysik; Physics; rymd- och plasmafysik; Space and Plasma Physics;

    Sammanfattning : This thesis deals with the development of the Jovian Neutrals Analyzer (JNA) for the Jupiter ICy moons Explorer (JUICE) mission to Jupiter, planned to launch in 2023. Jupiter, the largest planet in the Solar System, orbits the Sun at five times the distance from the Earth to the Sun, accompanied by dozens of moons, rings, and the largest object in the SolarSystem: the Jovian magnetosphere.

  5. 4. Particle image velocimetry in practice

    Författare :Torbjörn Green; Kristian Angele; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : 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. LÄS MER

  7. 5. Performance of image-based velocimetry in river flow – Large Scale PIV and PTV

    Författare :Trieu Hang; J. Gunnar I. Hellström; Mikael Sjödahl; Patrik Andreasson; Kristian Angele; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : River flow velocity is critical information for hydraulic and hydrological applications. Monitoring flow fields in near-plant waterways and river reach has wide engineering applications insustainable hydropower generation. LÄS MER
