  1. 1. Centrifugal Turbopumps - Flow Physics and Modelling

    University essay from Lunds universitet/Institutionen för energivetenskaper

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Kraft- och värmeteknologi

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

    Abstract : 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. READ MORE

  4. 3. A Preliminary Design Tool For Radial Compressors

    University essay from Lunds universitet/Institutionen för energivetenskaper

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

    Abstract : 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. READ MORE
