   Abstract : Density functional theory (DFT) calculations of polyethylene (PE) HVDC cable insulation have been performed for systems containing four different chemical impurities: acetophenone, cumene, $\alpha$-methyl styrene and $\alpha$-cumyl alcohol. Systems were generated by molecular dynamics (MD) equilibration at four different temperatures relevant for cable insulation applications: 277 K, 293 K, 343 K and 363 K. READ MORE

3. 2. 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
