  1. 1. Centrifugal Turbopumps - Flow Physics and Modelling

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Carl Eriksson; Hampus Henåker; [2021]
    Nyckelord :Centrifugal Pumps; Rocket Science; Turbopumps; Two-Zone Model; Impeller; Vaneless Diffuser; Vaned Diffuser; Technology and Engineering;

    Sammanfattning : Choices made in the early stages of a design process are crucial. They dictate many of the limitations and freedoms the designer has in later stages of the design. Informed decisions are therefore crucial at this stage. LÄS MER

  3. 2. Analytical prediction of turbocharger compressor performance: A comparison of loss models with numerical data

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Sergio Sanz Solaesa; [2016]
    Nyckelord :;

    Sammanfattning : One-dimensional models predict the performance of centrifugal compressor in short time, being a helpful design tool in the early design stages. They assume uniform flow through the compressor. Conservation of mass, momentum and energy and some empirical loss correlations are applied to estimate the real outputs. LÄS MER

  4. 3. CFD INVESTIGATION OF IMPELLER DIFFUSER INTERACTION EFFECTS ON RADIAL COMPRESSOR STAGE

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Armagan Kumlu; [2014]
    Nyckelord :CFD; impeller-diffuser interaction; radial compressor; centrifugal compressor; vaneless space;

    Sammanfattning : The effects of impeller-diffuser interaction are investigated through numerically simulating the modified wedge vane profiles. Steady and time-accurate, 3D- viscous RANSsolver is used to perform flow field computations. The original design is modified to obtain better aerodynamic performance. LÄS MER

  5. 4. A Preliminary Design Tool For Radial Compressors

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Johannes Schiff; [2013]
    Nyckelord :radial compressor; centrifugal compressor; turbomachinery design tool; impeller; vaneless diffuser; vaned diffuser; wedge diffuser; Technology and Engineering;

    Sammanfattning : The aim of this thesis has been to implement a computer program capable of modelling radial compressors. The work was conducted at the Division of Thermal Power Engineering, Department of Energy Sciences at the Faculty of Engineering, Lund University. With such a large field as radial compressors, some decomposition of the subject was necessary. LÄS MER
