  1. 1. Numerical Study of Fluid-Structure Interaction with Application to Oscillating Cylinders

    University dissertation from Mikhail Lazarkov, Magistratsvagen F55, 204, Lund

    Author : Mikhail Lazarkov; Lunds universitet.; Lund University.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lock-in.; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; synchronization; flow-induced vibration; LES; Volume of Solid method; Virtual Boundary method; vortex-shedding; confined cylinder; Fluid-structure interaction; wake;

    Abstract : Popular Abstract in Swedish The problem of fluid-structure interaction, occurring in many industrial and engineering applications, are of great importance, since interaction of a flow and a structure in it can lead to serious damages of the structure. The fluid-structure interaction gives rise to a variety of different physical phenomena such as flow-induced vibration, noise generation, etc. READ MORE

  2. 2. Fragmentation and waste rock compaction in small-scale confined blasting

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Daniel Johansson; Luleå tekniska universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil engineering and architecture - Geoengineering and mining engineering; Samhällsbyggnadsteknik och arkitektur - Geoteknik och gruvteknik; Gruv- och Berganläggningsteknik; Mining and Rock Engineering;

    Abstract : Sub-level caving (SLC) is an important mass mining method, used at LKAB e.g. The caved rock or debris at the SLC interface reduces the fragmentation and the swelling of the blasted ring and it dissipates the explosive energy. These phenomena may immobilize the blasted ring, causing ore losses. READ MORE

  3. 3. Dynamics of Exhaust Valve Flows and Confined Bluff Body Vortex Shedding

    University dissertation from KTH Royal Institute of Technology

    Author : Marcus Winroth; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk mekanik; Engineering Mechanics;

    Abstract : This thesis can be divided into two interconnected topics; engine exhaust-valve flows and confined bluff-body vortex shedding. When optimising engine flow systems it is common to use low order simulation tools that require empirical inputs, for instance with respect to flow losses across the exhaust valves. READ MORE

  4. 4. Utilization of Decomposition Techniques for Analyzing and Characterizing Flows

    University dissertation from KTH Royal Institute of Technology

    Author : Christian Carlsson; Lunds universitet.; Lund University.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decomposition techniques; Proper orthogonal decomposition; Dynamic mode decomposition; Extended dynamic mode decomposition; Swirl switching; Swirling flow; Low swirl burner; Fluid-structure interaction;

    Abstract : Popular Abstract in Swedish Vetskap om strömning av vätskor och gaser är viktigt i dagens samhälle, vilket inkluderar transport i rör, förbränning, och flödesinducerade vibrationer. På grund av sin flyktiga form är möjligheten att kontrollera flöden i diverse applikationer begränsad. READ MORE

  5. 5. Numerical Modelling of Some Engineering Heat Transfer Problems

    University dissertation from Division of Heat Transfer, Lund Institute of Technology

    Author : Daniel Eriksson; Lunds universitet.; Lund University.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy research; Energiforskning;

    Abstract : Engineering heat transfer problems are very often of a complex nature and most often no analytical solutions exist. One way to create solutions to such problems is to apply numerical methods. This study concerns heat transfer problems with coupled conduction, convection and thermal radiation. READ MORE
