  1. 1. Compressor Surge: Simulation, Modeling and Analysis

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Robin Massiquet; [2022]
    Nyckelord :Turbo compressor; Surge; Simulation; Modelling;

    Sammanfattning : The master thesis subject takes place in the automotive industry and specifically in the internal combustion engine area. The need of improving the efficiency of the engines leads to develop new technologies like turbo compressors. Some of the challenges to overcome are high rotational speed difficulties or extreme load and fatigue in the rotors. LÄS MER

  3. 2. Co-Simulation Development for Improved Cavitation Predictions in Oil-Hydraulics Systems : An investigation into the cavitating flow behavior of repetitive water hammers.

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Thisal Mandula Sugathapala; Twan Bakker; Rahul Gudur Suresh; Aryan Delir; [2022]
    Nyckelord :co-simulation; water hammer; cavitation;

    Sammanfattning : Numerical modeling of cavitation using computational software is a highly pursued topic of research due to its impact in different industrial sectors. While some industrial applications such as wastewater treatment and mineral processing are known to advantageously use this phenomena, it remains an unwanted process in others where it is known to induce vibration, reduce performance and cause structural damage.

  5. 4. Surge Modeling and Control of Automotive Turbochargers

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Oskar Leufvén; Johan Bergström; [2007]
    Nyckelord :Compressor; Mean Value Engine Modeling; Surge control; Surge line; Surge valve;

    Sammanfattning : Mean Value Engine Modeling (MVEM) is used to make engine control development less expensive. With more and more cars equipped with turbocharged engines good turbo MVEM models are needed. A turbocharger consists of two major parts: turbine and compressor. LÄS MER

  7. 5. Bypass Modeling and Surge Control for turbocharged SI engines

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Eric Wiklund; Claes Forssman; [2005]
    Nyckelord :Mean Value Engine Modeling; Bypass valve; Surge control; Wastegate; TOMOC;

    Sammanfattning : Since measurements in engine test cells are closely coupled with high costs it is of interest to use physically interpretable engine models instead of engine maps. Such engine models can also be used to do off-line tests of how new or altered components affects engine performance. LÄS MER
