  3. 2. Cable Shape Optimization - Drag Reduction of Cables Used in Marine Applications

    University essay from KTH/Teknisk mekanik

    Author : Simon Garpenquist; [2023]
    Keywords : Wind Tunnel Experiment; Computational Fluid Dynamics; Aerodynamic Forces; Drag Reduction; Shape Optimization; Flow around Cylinders; Yacht Racing;

    Abstract : It is important to understand the aerodynamic properties of tensioned cables (e.g. used in suspension bridges and yacht riggings), both for drag reduction and vibrational suppression purposes. READ MORE

  4. 3. A cross-correlation analysis of a warm super-Neptune using transit spectroscopy

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Elias Önerud; [2023]
    Keywords : Cross-correlation; cross-correlation spectroscopy; cross-correlation analysis; super-Neptune; astronomy; astrophysics; WASP-107; WASP-107 b; CRIRES ; SysRem; exoplanet; transmission spectrum; transit;

    Abstract : A study was made in order to deduce whether certain chemical species, namely water (H2O) and carbon monoxide (CO), are present in the atmosphere of the exoplanet WASP-107 b, which lies about 200 light-years away from Earth in the constellation Virgo. The project was carried out at Uppsala University at the Department of Physics and Astronomy. READ MORE

  5. 4. Active flow control of the turbulent boundary layer over a NACA4412 wing profile for skin friction drag reduction

    University essay from KTH/Teknisk mekanik

    Author : Giacomo Semprini Cesari; [2023]
    Keywords : Active flow control; drag reduction; numerical simulations; turbulent boundary layer; wings;

    Abstract : In the context of building a framework for active flow control of turbulent boundary layers in wings, a set of large-eddy simulation (LES) are implemented in OpenFOAM. The flow around a NACA4412 wing profile is simulated at 5° angle of attack and Re_c = 400˙000. READ MORE

  6. 5. Effektivisering av bygglogistik : Utmaningar

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Author : Haitham Al-Ameri; [2022]
    Keywords : Bygg; logistik; transport; miljö; politik; ekonomi; miljöpolitik; bränslepriser; byggbranschen; anläggning.;

    Abstract : Varierande styrmedel samt olika politiska mål har gett upphov till varierande i bygginvesteringar. Detta har i sig lett till olika utmaningar inom byggbranschen främst inom bygglogistik. Bygglogistik och dess delar ihop med byggmaterial representerar 61% av byggkostnaden. Under de senaste 10 åren har byggkostnaden bara ökat. READ MORE
