  1. 1. On Bicompositional Correlation

    Author : Jakob Bergman; Statistiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Joint correlation coefficient; Empirical confidence coefficient; Dirichlet distribution; Correlation; Composition; Compositional data; Random variate generation; Simplex;

    Abstract : A composition is a vector of positive components summing to a constant, usually taken to be 1. Hitherto the research on compositional correlation has mainly focused on the correlation between the components of composition. This thesis is concerned with modelling the correlation between two compositions. READ MORE

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

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

    Abstract : 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. READ MORE

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

    Author : Lasse Malmkjaer Christoffersen; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooling flow.; Correlation; Experiment; Reynolds number; Road Vehicle Aerodynamics; CFD; Scale model;

    Abstract : 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.

  4. 4. Extraction of Metal Values : Thermodynamics of Electrolyte Solutions and Molten Salts Extraction Process

    Author : Xinlei Ge; Seshadri Seetharaman; Katsunori Yamaguchi; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Electrolyte solutions; activity coefficient; osmotic coefficient; freezing point depression; boiling point elevation; Materials science; Teknisk materialvetenskap;

    Abstract : Over the past centuries, a number of process routes for extraction of metal values from an ore or other resources have been developed. These can generally be classifiedinto pyrometallurgical, hydrometallurgical or electrometallurgical routes. READ MORE

  5. 5. Development of a Noise-Based Method for the Determination of the Moderator Temperature Coefficient of Reactivity (MTC) in Pressurized Water Reactors (PWRs)

    Author : Christophe Demaziere; Chalmers University of Technology; []
    Keywords : point-kinetics; Decay Ratio DR ; Gamma-Thermometer GT ; temperature noise structure of the ; correlation length; boron dilution method; noise analysis; core calculations; dynamic reactor transfer function; moderator temperature coefficient MTC ;

    Abstract : The Moderator Temperature Coefficient of reactivity (MTC) is an important safety parameter of Pressurized Water Reactors (PWRs). In most countries, the so-called at-power MTC has to be measured a few months before the reactor outage, in order to determine if the MTC will not become too negative. READ MORE
