  1. 1. Permeability of non-crimp fabrics : a computational fluid dynamics approach

    Author : Markus Nordlund; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : In the present market for manufacturing of high performance structural parts for various applications such as aerospace, transportation, infrastructure, marine, sports and recreation, low weight, high performance composites are preferable. Non-Crimp Fabrics (NCFs) are often used for such applications due to its high mechanical properties and often cost effective production. READ MORE

  2. 2. Aerodynamic Design and Experimental Investigation of Short Nacelles for Future Turbofan Engines

    Author : Vinícius Tavares Silva; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultra-high-bypass turbofan; Computational Fluid Dynamics; powered nacelle.; Ultra-short nacelles; experimental; thrust-and-drag bookkeeping;

    Abstract : To achieve a higher propulsive efficiency, and hence reduced fuel burn and emissions, the next generation turbofan engines are expected to have higher bypass ratios and lower fan pressure ratios. However, the larger the bypass ratio, the larger becomes the fan and thus the nacelle. The result is an undesired increase in weight and nacelle drag. READ MORE

  3. 3. Experimental study of bubble dynamics and transport

    Author : Gunilla Andrée; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiforskning; Energy research; Particle Streak Photography; Shadowgraph; Particle Image Velocimetry; Bubble dynamics; bubble transport;

    Abstract : The thesis concerns experimental studies of bubble motion and the transport of large particles and bubbles. Bubbly flows are encountered in many engineering applications where the bubbles play an important role for the mass transfer between the phases, e.g. in stirred reactors. READ MORE

  4. 4. Molecular Dynamics Simulations of Fluid Lipid Membranes

    Author : Erik G. Brandt; Olle Edholm; Mats Wallin; Markus Deserno; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biological fluid dynamics; biomembranes; hydrodynamics; lipid bilayers; molecular dynamics; neutron spin echo;

    Abstract : Lipid molecules form thin biological membranes that envelop all living cells, and behave as two-dimensional liquid sheets immersed in bulk water. The interactions of such biomembranes with their environment lay the foundation of a plethora of biological processes rooted in the mesoscopic domain - length scales of 1-1000 nm and time scales of 1-1000 ns.

  5. 5. Combustion, Fluid Dynamics and Heat Transfer in Oxy-fuel and Air-Fired CFB boilers

    Author : Sadegh Seddighi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon Capture and Storage; Combustion; Circulating Fluidized Bed; Oxy-Fuel; Multi-Phase Reacting Flow; Boiler Design; Emission; Fluid Dynamics; Heat Transfer;

    Abstract : The studies described in this thesis develop and encode modeling tools for the design and scale-up of oxy-fuel circulating fluidized bed (CFB) boilers across a wide range of operational conditions. The modeling comprises fluid dynamics, combustion, and heat transfer and uses expressions that are proposed in this work or derived from the literature, together with experimental data obtained under both oxy-fuel-fired and air-fired conditions.
