  1. 11. Molecular Dynamics Simulations of Fluid Lipid Membranes

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

    Sammanfattning : 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.

  3. 12. A Large Eddy Simulation Based Fluid-Structure Interaction Methodology with Application in Hydroelasticity

    Författare :Andreas Feymark; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydroelasticity; subgrid modeling; large eddy simulation; trip model; fluid- structure interaction; numerical simulation; forced oscillation; naval architecture; hydrodynamics;

    Sammanfattning : The phenomenon of hydroelasticity is a subarea of Fluid-Structure Interaction (FSI) and of major importance in many engineering applications related to hydrodynamics and naval architecture e.g. LÄS MER

  4. 13. Hydrophysical processes governing brownification : A case study of Lake Bolmen, Sweden

    Författare :Clemens Klante; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Natural organic matter NOM ; Hydrodynamics; Lake; Hydrology; Drinking water production; Ecosystem;

    Sammanfattning : Access to water of good quality and quantity has become more challenging because of a changing climate, as well as an increase in the use of natural resources, which has lead to altered water chemistry. One of these changes is known as brownification, resulting from a higher organic matter content causing a yellow-brown color of surface waters. LÄS MER

  5. 14. Large eddy simulation of cavitating and non-cavitating flow

    Författare :Tobias Huuva; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high Reynolds number; Cavitation; turbulence; RANS; hydrodynamics; numerical simulation; modelling; DES; LES;

    Sammanfattning : Most marine configurations are subject to a number of complex and important hydrodynamic phenomena affecting the overall performance of the vessel, both regarding resistance and propulsive efficiency. In this thesis, the possibility of numerically simulating some of these phenomena is investigated. LÄS MER

  7. 15. Fermentative hydrogen and methane productions using membrane bioreactors

    Författare :Julius Akinbomi; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Encapsulation; Inhibition; hydrodynamics; hydrogen; methane; fruit flavour; Membrane bioreactor; Resursåtervinning; Resource Recovery;

    Sammanfattning : The role of energy as a stimulant for economic growth and environmental sustainabilityof any nation has made the focus on green fuels, including fermentative hydrogen (bioH2) andmethane (bioCH4), to be a priority for the World’s policy makers. Nigeria, as the most populousAfrican country, with worsening energy crisis, can benefit from the introduction of the bioH2 andbioCH4 technologies into the country’s energy mix, since such technologies have the potential ofgenerating energy from organic wastes such as fruit waste.
