  1. 1. Performance and model calibration ofhigh-pressure compressors

    University essay from KTH/Energiteknik

    Author : Antoine Brissaud; [2018]
    Keywords : ;

    Abstract : To fully determine the performances of high-pressure compressors (HPC), modeling and partial tests can beperformed to characterize its different operating conditions. Nevertheless, there are still noticeable errorsbetween the results of these models and the tests: deformations and differences can appear, and notably becauseof a modeling defect or the assumptions made during the analysis (measurement corrections for example).

  2. 2. A Spatial Syntax for Perceived Safety in Urban Environments : for Application in Urban Planning

    University essay from KTH/Geoinformatik

    Author : Nore Ottenby; [2017]
    Keywords : GIS; space syntax; perceived safety; urban planning; axial map; viewshed; GIS; space syntax; trygghet; stadsplanering; axialkarta; viewshed;

    Abstract : Perceived safety is an important aspect of urban planning and is generally treated as an objective account of the personal sense of safety of each individual. The subject is inherently diffuse and therefore problematic to understand and evaluate in its entirety. READ MORE

  3. 3. Tomographic reconstruction of subchannel void measurements of nuclear fuel geometries

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Magnus Ahnesjö; [2015]
    Keywords : tomography; void; nucler power; bwr;

    Abstract : The Westinghouse FRIGG loop in Västerås, Sweden, has been used to study the distribution of steam in the coolant flow of nuclear fuel elements, which is known as the void distribution. For this purpose, electrically heated mock-ups of a quarter BWR fuel bundles in the SVEA-96 geometry were studied by means of gamma tomography in the late 1990s. READ MORE

  4. 4. U-RANS Simulation of fluid forces exerted upon an oscillating tube array

    University essay from KTH/KTH/Farkost och flygAeroakustik

    Author : Lise Divaret; [2011]
    Keywords : Fluid-structure interaction; CFD; Forces; added mass; drag coefficient; Morison expansion; Unsteady Reynolds Averaged Navier Stokes simulations; Arbitrary Lagrange Euler model.;

    Abstract : The aim of this master thesis is to characterize the fluid forces applied to a fuel assembly inthe core of a nuclear power plant in case of seism. The forces are studied with a simplifiedtwo-dimensional model constituted of an array of 3 by 3 infinite cylinders oscillating in aclosed box. READ MORE
