  1. 1. Characterization of commercially pure titanium under supercritical conditions : By means of hybrid numerical-experimental approach

    University essay from KTH/Materialvetenskap

    Author : Ricardo Rodríguez; [2022]
    Keywords : ;

    Abstract : Material characterization was addressed by solving the inverse engineering problem to mechanical properties by means of finite element analysis and computational optimization. High-temperature and high strain-rate data from split Hopkinson pressure bar tests on commercially pure titanium were used in the study. READ MORE

  3. 2. On Control and stabilisation of floating wind platforms with the help of CFD analysis and the Magnus effect

    University essay from KTH/Numerisk analys, NA

    Author : Georg Neumüller; [2017]
    Keywords : ;

    Abstract : With new technologies and possibilities arising both in the renewable energy sector as well as in the field of Computational Fluid Dynamics, this thesis describes the simulation of vortex- induced vibrations for floating wind turbine platforms. The aim is to control and stabilize floating wind platforms with the help of CFD and the Magnus effect. READ MORE

  4. 3. Solvent adsorption in SFC : Adsorption of methanol under supercritical conditions

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper

    Author : Emelie Edström; [2015]
    Keywords : SFC; excess adsorption isotherm; methanol; tracer pulse;

    Abstract : Chromatography is a widely used separation technique including many different modes, for example supercritical fluid chromatography (SFC) which uses a supercritical fluid as mobile phase. A supercritical fluid is achieved when a substance is subjected to a temperature and pressure above the critical point and the boundary between the liquid phase and gas phase is erased. READ MORE

  5. 4. Characterization of flow regimes between supercritical carbon dioxide and water in microfluidics, comparing coated and mechanically modified channels.

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Niklas Rogeman; [2014]
    Keywords : ;

    Abstract : Water and supercritical carbon dioxide have different wetting angles to a glass surface, where water has a lower angle. In a microfluidic channel, the lower wetting angle draws the water to surround the supercritical carbon dioxide and the supercritical carbon dioxide therefore easily form droplets or segments if the flow rate is low.
