    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Pierre Collard; [2022]
    Keywords : ;

    Abstract : For more than half a century, humanity has achieved the feat of extracting itself from the earth's atmosphere and sailing into space, broadening the spectrum of knowledge and curiosity. Although space market seemed mastered and stable the arrival of new private players has reorganized the sector through new technological choices. READ MORE

  4. 3. CFD simulation of gas turbine ventilation and gas dilution

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Lokesh Sathyanarayana; [2022]
    Keywords : CFD; Gas dilution; Gas turbines; Ventilation;

    Abstract : 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. READ MORE

  5. 4. LES modelling of spray combustion

    University essay from Lunds universitet/Institutionen för energivetenskaper

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

    Abstract : 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.
