    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiforskning; plasma; Energy research; fluiddynamik; Gaser; fluid dynamics; plasmas; Gases; Particle image velocimetry; Liquid crystal thermography; ribbed channel; heat transfer; turbulence properties; separated flow; coherent structures;

    Abstract : The main concern of this thesis is to experimentally investigate the turbulent flow and heat transfer in a ribbed channel. Such flows are encountered in many engineering applications, e.g., gas turbine cooling. READ MORE

  6. 14. On methods for estimating oceanic flow

    Author : Jenny A. U. Nilsson; Peter Lundberg; Peter Sigray; Bert Rudels; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ocean monitoring techniques; Barotropic flow; Baroclinic flow; Hydraulic theory; Baltic Sea; Bahía de Concepción; Oceanography; Oceanografi; Oceanography; oceanografi;

    Abstract : The aim of this thesis was to estimate and possibly quantify ocean flow by utilizing conventional and novel observational methods as well as model results. Motionally induced voltages, from a cable-based observational system in the Baltic Sea, were analysed to determine their utility for ocean monitoring. READ MORE

  7. 15. Modelling of Turbulent Flow and Heat Transfer for Building Ventilation

    Author : Peng Shia-Hui; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; large eddy simulation; turbulent buoyant convection; ventilation performance assessment; purging flow rate; SGS modelling; ventilation flow; stochastic Markov chain model; turbulence modelling; LRN k-w model; two-equation models; building ventilation; transfer probability; transition regime; modified SGS buoyancy model; energy backscatter;

    Abstract : This thesis contributes to studies on the assessment of building ventilation performance and the development of turbulence models accounting for Low-Reynolds-number (LRN) effects and buoyant convection with heat transfer. Assessments of building ventilation performance are discussed with respect to indoor air distribution and passive contaminant dispersion. READ MORE
