  1. 6. EXPERIMENTAL STUDY ON PRESSURE LOSSES IN ADDITIVELY MANUFACTURED AND MACHINED ORIFICES : A rectangular geometry of additively manufactured MA 247 orice and a circular geometry ofmachined AW-6082 T6 orifice study

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Jayadev Nambisan; [2020]
    Nyckelord :Cooling; Fluid Dynamics; Additive Manufacturing; Pressure Losses; Fluid Dynamics Testing; Machining; Gas Turbines; Gas Turbine Cooling; Nouveau Geometries;

    Sammanfattning : Gas turbine components for cooling purposes including other unique and complex three-dimensional designs could be made explicitly possible through additive manufacturing using SLM technology in contrary to the conventional machining processes. Nevertheless, the surface roughness and subsequently the friction factor governs thepressure drop in these components implicitly, thus, influencing the secondary air flow system of a gas turbine.

  3. 7. Automating the CAD to Virtual Reality Pipeline for Assembly Simulation

    Master-uppsats, Linköpings universitet/Maskinkonstruktion

    Författare :Gustav Eriksson; Anton Engberg; [2020]
    Nyckelord :CAD; Unreal Engine; Virtual Reality; VR; Import; Automation; Assembly; Simulation; VR Training;

    Sammanfattning : Virtual reality is emerging as a valuable tool in the manufacturing industry, as it allows engineers to place themselves in a virtual environment in which they can inspect and evaluate their 3D designs, providing a sense of scale not available through a 2D screen. Siemens Industrial Turbomachinery AB currently uses physical prototypes to assess whether their designs work from an assembly perspective, which can be expensive and time consuming to make and are often downscaled.

  4. 8. Construction of a Heat Transfer Rig based on Energy Balance for Rapid Production of Correlations for Additively Manufactured Geometries

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Joaquin Quesada Zeljkovic; [2019]
    Nyckelord :;

    Sammanfattning : This thesis has set the first milestones towards building a Nusselt number correlation that adapts to the current state of art designing and manufacturing processes at Siemens Industrial Turbomachinery AB, focusing on cooling mini-channels produced with Additive Manufacturing.  Additive manufacturing (AM), also known as 3D printing, is a gamechanger technology that has revolutionised manufacture and design know-how, bringing down production cost, time and waste.

  5. 9. Kvalitetsarbete inom mätteknik med FARO-arm

    Uppsats för yrkesexamina på grundnivå, Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik

    Författare :Daniel Bengtsson; Karin Gustafsson; [2019]
    Nyckelord :Mätinstrument; gasturbiner;

    Sammanfattning : Examensarbetet har utförts på Siemens Industrial Turbomachinery AB i Trollhättan. Företaget tillverkar brännkammare till gasturbiner. Syftet med arbetet har varit att undersöka om kvalificerade mätningar kan utföras med Siemens Industrial Turbomachinery AB:s mätinstrument. Denna undersökning har utförts genom en mätsystemanalys.

  7. 10. Evaluation of CFD Methods for Prediction of Total Temperature and Total Pressure Distribution in Gas Turbines

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Lars Fredrik Wahlgren; [2019]
    Nyckelord :;

    Sammanfattning : This thesis work was performed as a collaboration between the Royal Institute of Technology in Stockholm and Siemens Industrial Turbomachinery in Finspång. It was undertaken with the purpose of investigating the use of CFD methods in ANSYS CFX to predict flow mixing in gas turbines. LÄS MER
