  1. 1. The Aerodynamic Correlation of a Scale Model with a Full Size Car

    Författare :Lasse Malmkjaer Christoffersen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooling flow.; Correlation; Experiment; Reynolds number; Road Vehicle Aerodynamics; CFD; Scale model;

    Sammanfattning : Reducing the Worlds consumption of energy has become an important part of the current political and environmental debate. The reasons are obvious: World population is increasing, continued growth in living standards, finite availability of resources and finally green house gas emissions from energy production have to be brought down to stabilize temperatures.

  3. 2. Uncertainty and correlation modeling for load flow analysis of future electricity distribution systems : Probabilistic modeling of low voltage networks with residential photovoltaic generation and electric vehicle charging

    Författare :Umar Hanif Ramadhani; Joakim Widén; Joakim Munkhammar; Sarah Rönnberg; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Probabilistic load flow; Electricity distribution systems; Uncertainty model; Correlation model; Photovoltaics; Electric vehicle; Residential buildings; Hosting capacity; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

    Sammanfattning : The penetration of photovoltaic (PV) and electric vehicles (EVs) continues to grow and is predicted to claim a vital share of the future energy mix. It poses new challenges in the built environment, as both PV systems and EVs are widely dispersed in the electricity distribution system. LÄS MER

  4. 3. On Film Cooling of Turbine Guide Vanes : From Experiments and CFD-Simulations to Correlation Development

    Författare :Hossein Nadali Najafabadi; Matts Karlsson; Esa Utriainen; Mats Kinell; Valery Chernoray; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Film Cooling; Gas Turbine; Correlation; CFD; Cylindrical holes; Fan-shaped Holes;

    Sammanfattning : To achieve high thermal efficiency in modern gas turbines, the turbine-inlet temperature has to be increased. In response to such requisites and to prevent thermal failure of the components exposed to hot gas streams, the use of different cooling techniques, including film cooling, is essential. LÄS MER

  7. 5. Calibration and Reduction of Large-Scale Dynamic Models - Application to Wind Turbine Blades

    Författare :Majid Khorsand Vakilzadeh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; maximum likelihood estimator; model reduction; finite element model calibration; Bayesian model calibration; Verification and validation; wind turbine blade; logarithmic least square estimator; large-scale dynamics model; SWPTC;

    Sammanfattning : This thesis investigates the validity of structural dynamics models of wind turbine blades. An outlook on methods for model calibration to make models valid for their intended use is presented in the thesis. The intention is to make the models valid for robust predictions. The model validity is here assessed to be of hierarchical dual level. LÄS MER
