  1. 1. µPIV Measurement of Grease Velocity Profiles

    Author : Jinxia Li; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Lubricating grease is commonly applied to lubricate e.g. rolling bearings, seals and gears. Grease has some clear advantages over lubricating oil. READ MORE

  2. 2. Formation of non-metallic inclusions and the possibility of their removal during ingot casting

    Author : Lars Ragnarsson; Sichen Du; Carlo Mapelli; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ingot casting; tool steel; inclusion; runner; refractory; erosion; casting powder; cold model; argon shroud; reoxidation; oxygen measurement; CFD; PIV; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : The present study was carried out to investigate the formation and evolution of non-metallic inclusions during ingot casting. Emphasize have been on understanding the types of inclusions formed and developed through the casting process and on the development of already existing inclusions carried over from the ladle during casting.

  3. 3. Experimental and computational studies of turbulent separating internal flows

    Author : Olle Törnblom; Arne V. Johansson; Michel Stanislas; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; turbulence; flow separation; turbulence modelling; asymmetric diffuser; boundary layer; PIV; vortex generator; separation control; Fluid mechanics; Strömningsmekanik;

    Abstract : The separating turbulent flow in a plane asymmetric diffuser with 8.5 degrees opening angle is investigated experimentally and computationally. The considered flow case is suitable for fundamental studies of separation, separation control and turbulence modelling. READ MORE

  4. 4. Experimental Studies of Turbulent Mixing in Impinging Jets

    Author : Rong Ding; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LDV; Gases; fluid dynamics; plasmas; Gaser; fluiddynamik; plasma; PIV LIF; TR- LIF; TR- PIV; perturbed- and swirling- impinging jets; passive control; frequency spectrum; turbulent fluxes; impinging jets; turbulent mixing;

    Abstract : This thesis concerns the experimental study of mixing and flow characteristic in turbulent circular impinging jets without and with jet orifice manipulators (i.e. passive-fixed perturbations atthe nozzle exit), without and with swirl. READ MORE

  5. 5. Laser Based Flow Measurements to Evaluate Hydraulic Conditions for Migrating Fish and Benthic Fauna

    Author : S M Sayeed Bin Asad; Staffan Lundström; J. Gunnar I. Hellström; Anders G. Andersson; Berhanu Mulu Geberkiden; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fish Migration; Step Cylinder; Shedding; Vortex Street; Shear stress; PIV; benthic fauna; river; stones; Strömningslära; Fluid Mechanics;

    Abstract : Hydropower is one of the main sources for Sweden’s energy, which is clean and renewable. It is a clean energy source because no fuels are burned which does not pollute the air and it is a renewable energy source as it only uses natural water cycle for generating energy. READ MORE
