  4. 3. Laser Diagnostics Applied to Lean Premixed Swirling Flames - Simultaneous Flow Field and Scalar Measurements

    Författare :Per Petersson; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Volumetric Velocimetry; Low-swirl Flames; Premixed Flames; Turbulent Combustion; Particle Image Velocimetry; Laser Diagnostics; A.2014:Petersson; Combustion Diagnostics;

    Sammanfattning : The work reported here includes experimental studies of lean premixed swirling flames. Various laser-based optical diagnostic techniques were used to collect information under different operational conditions. Combined flow- and scalar field measurements were performed at high repetition rates for detailed studies of the turbulent flames. LÄS MER

  5. 4. A Real-Time Soft Shadow Volume Algorithm

    Författare :Ulf Assarsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; three-dimensional graphics and realism; shading; pixel shaders; graphics hardware; shadowing; soft shadows; computer graphics;

    Sammanfattning : Rendering of shadows is a very important ingredient in three-dimensional graphics since they increase the level of realism and provide cues to spatial relationships. Area or volumetric light sources give rise to so called soft shadows, i.e., there is a smooth transition from no shadow to full shadow. LÄS MER

  7. 5. Flow structures in solid-liquid suspensions in mixing and confined jets

    Författare :Matthias Eng; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis is an investigation of the influence of solid particles on different liquid flow systems. Large-scale periodic fluctuations such as macro instabilities (MI) and particle cloud dynamics in a mixing vessel and confined jets were studied experimentally and compared to numerical results from CFD simulations.
