  1. 1. Experimental Investigation of the Influence of Local Flow Features on the Aerodynamic Damping of an Oscillating Blade Row

    Författare :Antonio Sanz Luengo; Torsten Fransson; Damian Vogt; Guillermo Paniagua; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbomachinery; Aeroelasticity; Flutter; Experimental Aerodynamics; CFD; Local Flow Features; Influence Coefficient; Linearity Assumption; Aerospace Engineering; Flyg- och rymdteknik;

    Sammanfattning : The general trend of efficiency increase, weight and noise reduction has derived in the design of more slender, loaded, and 3D shaped blades. This has a significant impact on the stability of fan, and low pressure turbine blades, which are more prone to aeroelastic phenomena such as flutter. LÄS MER

  3. 2. Blood Flow variations in Large Arteries due to non-Newtonian rheology

    Författare :Stevin van Wyk; Laszlo Fuchs; Staffan Lundström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blood; Rheology; Viscosity; non-Newtonian; CFD; Bifurcations; Unsteadiness; Wall Shear Stress; Atherosclerosis;

    Sammanfattning : The blood is a complex fluid that contains, in addition to water, cells, macro-molecules and a large number of smaller molecules. The physical properties of the blood are therefore the result of non-linear interactions of its constituents, which are influenced by the local flow field conditions. LÄS MER

  4. 3. Specific surface area of some minerals commonly found in granite

    Författare :Isabelle E. Dubois; Maria E. Malmström; Bo Strömberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Granite; Mineral; Surface area; BET; Sorption; Particle size;

    Sammanfattning : The specific surface area, determined by the BET method, is a parameter often used to scale results of mineral studies of surface reactions in terms of rate and capacity to the field scale. Such extrapolations of results from small-scale laboratory experiments to the field-scale are important within many environmental applications. LÄS MER

  5. 4. Numerical methods for the calibration problem in finance and mean field game equations

    Författare :Love Lindholm; Anders Szepessy; Lina von Sydow; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis contains five papers and an introduction. The first four of the included papers are related to financial mathematics and the fifth paper studies a case of mean field game equations. LÄS MER

  7. 5. Nuclear data uncertainty propagation for a lead-cooled fast reactor: Combining TMC with criticality benchmarks for improved accuracy

    Författare :Erwin Alhassan; Henrik Sjöstrand; Rochman Dimitri; Michael Österlund; Stephan Pomp; Christophe Demaziere; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tillämpad kärnfysik; Applied Nuclear Physics;

    Sammanfattning : For the successful deployment of advanced nuclear systems and for optimization of current reactor designs, high quality and accurate nuclear data are required. Before nuclear data can be used in applications, they are first evaluated, benchmarked against integral experiments and then converted into formats usable for applications. LÄS MER
