  1. 21. Numerical Modelling and Sensitivity Analysis of Tunnel Deformations in London Clay

    University essay from KTH/Jord- och bergmekanik

    Author : Malin Sandström; [2016]
    Keywords : Small-strain stiffness; Mohr-Coulomb; Plaxis; sensitivity analysis; tunnels; London Clay;

    Abstract : In dense cities, the interactions between all structures, from tall skyscrapers to complex underground tunnel systems, need to be carefully analysed as soon as a new project is considered. This is necessary because of the stress changes in the soil induced by each new construction. READ MORE

  6. 25. 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
