    University dissertation from Karlskrona : Blekinge Institute of Technology

    Author : Maria Bäcke; Blekinge Tekniska Högskola.; [2011]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; power; digital games; online world; Second Life; virtuality; reality; role-play; hierarchy; authority; governing; subversion; performance; online worlds; virtual worlds; virtual; digital space; rules; hierarchies; negotiation; make-believe;

    Abstract : This study investigates how the members of four different role-playing communities on the online platform Second Life perform social as well as dramatic roles within their community. The trajectories of power influencing these roles are my main focus. READ MORE

  2. 2. 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

  3. 3. Simulations of turbulent boundary layers with suction and pressure gradients

    University dissertation from KTH Royal Institute of Technology

    Author : Alexandra Bobke; KTH.; KTH.; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; boundary layers; near-wall turbulence; history effects; asymptotic suction boundary layers; large-eddy simulation;

    Abstract : The focus of the present licentiate thesis is on the effect of suction and pressure gradients on turbulent boundary-layer flows, which are investigated separately through performing numerical simulations.The first part aims at assessing history and development effects on adverse pressure-gradient (APG) turbulent boundary layers (TBL).

  4. 4. Multiscale methods for simulation of paper making

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Gustav Kettil; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Paper making; Numerical upscaling; Lay down simulations; Virtual paper sheets; Fiber network model; Forming fabric flow; Fiber suspension flow; Fiber-fiber interaction; Multiscale methods; Fluid structure interaction;

    Abstract : In this work, multiscale methods for simulation of paper making are developed. The emphasis is on simulation of the paper forming process and simulation of the mechanical properties of paper sheets. To simulate paper forming, a novel fiber-fiber interaction method is proposed.

  5. 5. Turbulent Shear Flow Experiments: Design of Natural Convection Rig and LDA Measurement in Swirling Jets

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Abolfazl Shiri; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-Similar Solution; Natural Convection Boundary Layer; Axisymmetric Jet; Laser Doppler Anemometry; Swirl Number;

    Abstract : This work consist of two sections. In the first part, a facility has been installed and modified from an existing rig in order to measure velocity and temperature field of axisymmetric turbulent natural convection boundary layers. With using laser doppler anemometry and cold wire resistance thermometry. READ MORE
