  1. 16. CFD simulation of gas turbine ventilation and gas dilution

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Lokesh Sathyanarayana; [2022]
    Nyckelord :CFD; Gas dilution; Gas turbines; Ventilation;

    Sammanfattning : Gas turbine engines are one of the primary sources of electricity currently in the world. The assembly consists of multiple subsystems all of which are placed within an acoustic enclosure. Dilution ventilation is a widely used and recommended means of protection against the risk of explosion within gas turbine acoustic enclosures. LÄS MER

  3. 17. Dynamic Modelling of the Patient Circuit for High Frequency Ventilation

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Samuel Eriksson; [2022]
    Nyckelord :Mechanical ventilation; high frequency ventilation; patient circuit dynamics; parameter estimation; system identification; Mekanisk ventilation; högfrekvent ventilation; patientkretsens dynamik; parameterestimering; systemidentifiering;

    Sammanfattning : Artificial breathing is vital when it comes to treatment of critically ill patients where the natural breathing mechanism is insufficient. With the help of mechanical ventilators, the natural breathing mechanism of the patient can be assisted or even exchanged with the artificial breathing from the machine. LÄS MER

  4. 18. Solceller på Västergårdsgymnasiet : En förstudie för att implementera solceller och energilagring ur ett ekonomiskt perspektiv

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Tim Gyulanszky; [2022]
    Nyckelord :solceller; energilagring; vätgas; litium-jon; flödesbatteri;

    Sammanfattning : The purpose of the project was to carry out a study of a potential solar cell facility at Västergårdsgymnasiet. Previous studies have established that there is the greatest potential for electricity production during the summer period, which coincides with the load at its lowest. LÄS MER

  5. 19. Modelling and Evaluation of a Waste Incineration Flue Gas Treatment Process

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Sandra Arvidsson; [2022]
    Nyckelord :Flue gas treatment; Limestone wet flue gas desulphurization; FGD; Waste incineration; Scaling; Modelling; Simulation; Aspen Plus; Chemical Engineering; Technology and Engineering;

    Sammanfattning : As environmental awareness is raised, flue gas treatment is gaining more interest and stricter legislation on emissions pushes technological development. Sysav has a waste incineration plant with a flue gas cleaning process which includes removal of acid gases. LÄS MER

  7. 20. LES modelling of spray combustion

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Arvid Åkerblom; [2021]
    Nyckelord :Gas Turbine; CFD; Large Eddy Simulation; Lagrangian Particle Tracking; Chemical Kinetics; Reaction Mechanism; Combustion; OpenFOAM; CHEMKIN; Technology and Engineering;

    Sammanfattning : Computational fluid dynamics is a powerful method for understanding the flow and combustion that occurs inside aircraft engines and will be a key tool in the transition from conventional fossil-based fuel to sustainable alternatives. Because conventional fuels have been more widely researched, an attempt at simulating the combustion of alternative fuels should be preceded by the development of a method that is capable of accurately simulating the combustion of a conventional fuel.
