  3. 2. Electronic structure calculations of defects in diamond for quantum computing : A study of the addition of dopants in the diamond structure

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Diana Elisa Murillo Navarro; [2019]
    Keywords : Density Functional Theory; Quantum computing; Diamond; Dopants; Quantum physics; NV color center;

    Abstract : When doing computations on the negatively (positively) charged NV-center in diamond, the common procedure is to add (subtract) an electron from the system. However, when using periodic boundary conditions, this addition/subtraction of an electron from the supercell would result in a divergent electrostatic energy. READ MORE

  4. 3. Wind tunnel blockage corrections forwind turbine measurements

    University essay from KTH/Mekanik

    Author : Pieter Inghels; [2013]
    Keywords : Wind tunnel; wind turbine; numerical model; measurements; blockage; empirical correction scheme;

    Abstract : Wind-tunnel measurements are an important step during the windturbinedesign process. The goal of wind-tunnel tests is to estimate theoperational performance of the wind turbine, for example by measuringthe power and thrust coecients. Depending on the sizes of both thewind turbine and the test section, the eect of blockage can be substantial. READ MORE

  5. 4. An Experimental Study on Global TurbineArray Eects in Large Wind Turbine Clusters

    University essay from KTH/Mekanik

    Author : Patrik Berkesten Hägglund; [2013]
    Keywords : GTAE; Global Turbine Array Eects; Wind tunnel; Reynolds number; Tip speed ratio; Thrust coecient; Induction factor; Turbine model; Wake eects; Wind farm; Aerodynamic scaling; Thrust measurement; Boundary corrections; Velocity prole;

    Abstract : It is well known that the layout of a large wind turbine cluster aects the energyoutput of the wind farm. The individual placement and distances betweenturbines will in uence the wake spreading and the wind velocity decit. READ MORE
