  1. 1. Automated High-Temperature Pressure Sensor Verification and Characterization

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Algirdas Bartkevicius; [2023]
    Nyckelord :Pressure sensor; sensor verification; sensor characterization; piezoelectric sensor; dynamic pressure sensor;

    Sammanfattning : Gas turbines are widely used in power generation. Monitoring pressure variations in the combustion chamber allows for real-time assessment of the turbines performance, and can be used to optimize combustion processes, leading to reduced emissions. LÄS MER

  3. 2. CFD investigation of a unit cell inside a Plate Heat Exchanger

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Mattias Ly; [2023]
    Nyckelord :Plate Heat Exchanger; CFD; Computational Fluid Dynamics; LES; Large Eddy Simulation; Periodic; Unit Cell; Technology and Engineering;

    Sammanfattning : A numerical investigation of the unit cell approach has been done to reduce the computational cost for CFD (Computational Fluid Dynamics) of plate heat exchangers (PHE) at Alfa Laval. The reduced cost would enable LES (Large Eddy Simulation) to be done which would give a more detailed and accurate insight into the flow and heat transfer processes of the PHE. LÄS MER

  4. 3. Early Stage Design of a Prefilmer at Siemens Energy : Numerical and Experimental Methodology

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Jean-Pierre Hamzo; [2023]
    Nyckelord :CFD; gas-turbine; computational fluid dynamics; atomizer; prefilmer; RANS; LES; multi-phase; experimental; numerical; atomization; spray characteristics; drop breakup; liquid fuels; liquid films;

    Sammanfattning : Design of atomizers for gas-turbine purposes are an important ordeal. The per-formance of the atomizer directly impacts the efficiency of the gas-turbine, andconsequently, the energy extracted from the turbine. Furthermore, the design ofthe atomizer can have an impact on reducing toxic emissions. LÄS MER

    Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Alexander Luukas; [2022]
    Nyckelord :Optimized steam sootblowing; superheaters; fouling; boiler efficiency; Waste fueled boiler; Overlapping sooting sequence; sotoptimering; ångsotning; överhettare; slaggning; överlappande sotblåsning; avfallspanna; pannverkningsgrad;

    Sammanfattning : The EU waste hierarchy includes energy recovery facilities where waste is used as fuel in combined heat- and powerplants. When waste is incinerated can the thermal energy be used in for example, district heating networks and or electricity generation. LÄS MER

  7. 5. Fault current injection from Inverter Based Generation in the distribution grid : A case study of distribution grid on the Swedish island of Gotland

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Farsad Mansori; [2022]
    Nyckelord :Distribution generator; Inverter-Based Distributed Generation; Inverter Based Generation; DFIG; PSCAD; Distribution grid; Overcurrent protection;

    Sammanfattning : This work proposes recommendations for new guidelines for fault current injection on a distribution grid. These guidelines will help improve the transition towards renewable electrical energy generation. LÄS MER
