  1. 16. Hydrogen-Methane combustion modeling in the burner of the SGT-800 Siemens Energy gas turbine

    University essay from KTH/Teknisk mekanik

    Author : Nikolaos Bozikis; [2022]
    Keywords : Engineering mechanics; fluid dynamics; CFD; combustion modeling; industrial gas turbines;

    Abstract : Industrial gas turbines constitute an integral part of today’s electricalpower production infrastructure. Reacting gas flows in these machines arevery interesting and complex in nature since they exhibit highly turbulentbehaviour which is strongly coupled to the chemical reaction dynamics. READ MORE

  3. 17. Exterior ballistics analysis for rocket propelled KE-penetrator - A conceptual simulation study within fluid mechanics and flight mechanics

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Emil Wegberg; [2022]
    Keywords : Exterior ballistics; fluid mechanics; high-speed aerodynamics; CFD; RANS; conceptual design; Ytterballistik; strömningsmekanik; höghastighetsaerodynamik; CFD; RANS; konceptuell design;

    Abstract : This study has investigated the conceptual feasibility of a rocket propelled kinetic energy penetrator (KEP), designed for the handheld recoilless rifle Carl-Gustaf® 84 mm calibre system, from an exterior ballistics perspective. The methodology is based upon evaluating the aerodynamic properties of different conceptual design proposals through CFD-simulations and then performing trajectory analysis to assess their exterior ballistic performance.

  4. 18. Aeroengine transients in altitude test facility

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

    Author : Baptiste VILLENEUVE; [2022]
    Keywords : ;

    Abstract : Altitude test facilities offer a safe and reliable way to perform a wide variety of tests on aircraft engine. Among them, aeroengine transients represent a necessary step in the certification and qualification of engines. READ MORE

  5. 19. Rotational Properties of Lee-Huang-Yang Bosonic Condensates from One to Two Dimensions

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Hjalmar Holmström; [2022]
    Keywords : BEC; Bose-Einstein condensate; quantum fluid; Quantum mechanics; LHY; LHY-fluid; Lee-Huang-Yang; Rotating BEC; BEC droplet; Physics and Astronomy;

    Abstract : This thesis covers the work of a numerical examination of the rotational properties of a two-component Bose-Einstein condensate (BEC) utilizing the beyond mean-field extended Gross-Pitaevskii equation for a specified set of parameters. These parameters are chosen to cancel the strength of the mean-field interaction, which makes the system predominantly governed by the next order beyond the mean-field Lee-Huang-Yang (LHY) term.

  6. 20. Multidisciplinary Modelling of Water Piston Oscillations in Wave Energy Converters : Assessment of Flow Resistance Through CFD Modelling with Fluid Structure Interactions

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Linnéa Tebelius; [2022]
    Keywords : Fluid Mechanics; Point Absorber; CFD; WEC; Waves4Power; Strömnigsmekanik; Point Absorber; CFD; WEC; Waves4Power;

    Abstract : As the world’s need for electricity increases, so does its demand for sustainable energy with low to no greenhouse gas emissions. One of these renewable sources of energy is the Ocean which is one of the world’s largest and most predictable energy source, where the extraction of energy can be from waves or tidal current, with zero greenhouse gas emissions during production.
