  2. 1. Air jets in ventilation applications

    Author : Yue Zou; KTH; []
    Keywords : Air jet; velocity; ventilation; CFD; measurement;

    Abstract : The purpose of air distribution systems for HVAC is tocreate proper air quality and thermal conditions in an occupiedzone. In mixing type air distribution systems air is suppliedinto a room through various types of outlets and distributed byturbulent air jets. These air jets are the primary factorsaffecting room air motion. READ MORE

  4. 2. µPIV Measurement of Grease Velocity Profiles

    Author : Jinxia Li; Henrik Åström; Luleå tekniska universitet; []
    Keywords : 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

  5. 3. Flow Field and Fibre Fractionation Studies in Hydrocyclones

    Author : Jonas Bergström; Bo Norman; Mark Martinex; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibre suspension; fractionation; hydrocyclone; measurement technique; velocity measurement; shear forces; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : Hydrocyclones can be used to fractionate fibres according to their papermaking potential. The obtained fractions typically differ in fibre wall thickness and/or degree of fibre treatment. Despite a multitude of potential application scenarios, the process has so far had little commercial success. READ MORE

  7. 5. Ballistic Imaging of Transient Phenomena in Turbid Media

    Author : David Sedarsky; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mie scattering; Laser Combustion Diagnostics; Imaging; Spray Diagnostics; Turbid Media; Velocity;

    Abstract : Ballistic imaging (BI) was developed as an optical diagnostic capable of ascertaining velocity and spatial information within dense sprays with relevance to liquid-fuel injection and combustion. This development includes a full model of light scattering within the complete imaging system, enabling the performance of the instrument to be examined, optimized and quantified. READ MORE
