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

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

    Abstract : 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. READ MORE

  4. 7. Experimental and Numerical Investigations of Confluent Round Jets

    Author : Klas Svensson; Bahram Moshfegh; Patrik Rohdin; Bengt Sundén; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Confluent jets; Multiple jet array; Jet interactions; Confluent Core Zone CCZ ; Particle Image Velocimetry PIV ; Laser Doppler Velocimetry LDA ; Computational Fluid Dynamics CFD ; Response Surface Methodology;

    Abstract : Unconfined multiple interacting confluent round jets are interesting from a purely scientific point of view, as interaction between neighboring jets brings additional complexity to the flow field. Unconfined confluent round jets also exist in various engineering applications, such as ventilation supply devices, sewage disposal systems, combustion burners, chemical mixing or chimney stacks.

  6. 9. Numerical Study of Dispersed Two-phase Flows

    Author : Zhilei Wu; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; Teknik; Technological sciences; Eulerian Lagrangian model.; Eulerian Eulerian model; Lagrangian Particle Tracking; Large Eddy Simulation; Two-phase flow; Particle Image Velocimetry; applied thermodynamics; Termisk teknik; termodynamik;

    Abstract : This thesis considers the numerical study of dispersed two-phase flows.Numerical simulations have been done to investigate the particle trasportation/dispersion effect in turbulent two-phase flows. Both turbulent bubble/water flows and turbulent particle/air flows are studied. READ MORE

  7. 10. Fluid Mechanics of Solid-Liquid Suspensions – An Experimental and Numerical Study

    Author : Torbjörn Virdung; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multiphase; soalescence; confined jet; computational fluid dynamics; stirred vessel; laser doppler velocimetry; particle image velocimetry; solid-liquid suspension; pitched blade; gas-liquid;

    Abstract : Multiphase flows are common in many applications in chemical, mineral, biochemical and several other process industries. Examples of equipment in which multiphase flows are encountered are stirred vessels and multiphase jets, in which suspensions are agitated by an impeller in the former case and distributed through a nozzle in the latter.
