  1. 1. 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. 2. Costly Black-Box Optimization with GTperform at Siemens Industrial Turbomachinery

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : André Malm; [2022]
    Keywords : Black-Box Optimization; GTperform; STG-800; Simulated Annealing; Gradient Descent;

    Abstract : The simulation program GTperform is used to estimate the machine settings from performance measurements for the gas turbine model STG-800 at Siemens Industrial Turbomachinery in Finspång, Sweden. By evaluating different settings within the program, the engineers try to estimate the one that generatesthe performance measurement. READ MORE

  4. 3. Material Supply Risks for the Energy Transition: A Quantitative Analysis of Resources, Production Concentration and Geopolitical Risks

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Ria Pozybill; [2022]
    Keywords : Sustainable development; Critical minerals; Geopolitical risks; Cobalt; Rare earths; Lithium;

    Abstract : The Paris Agreement aims to limit the global temperature to below 2°C above the pre-industrial level. In order to achieve this target, almost 200 countries committed to Nationally Determined Contributions to reduce their greenhouse gas emissions. Diverse strategies are applied to achieve the necessary emissions reductions. READ MORE

  5. 4. Experimental Investigation of the Thermal Performance and Pressure Loss in Additively Manufactured mini-channels

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Anna Nyhlen; [2021]
    Keywords : ;

    Abstract : Industrial gas turbines reach temperatures of 1500-2000K at high rotational velocities which means that much effort is spent on the design of an efficient cooling system. With the recent advances of the additive manufacturing (AM) industry, new design opportunities have open up for many industries and applications, including the design of cooling systems. READ MORE

  6. 5. Transient Performance of Siemens SGT-750 and SGT-800 : Modeling and Simulations of Industrial Gas Turbines on Island Grids

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Alexander Raddum; [2020]
    Keywords : Gas Turbine; Transients; Simulation;

    Abstract : Distributed energy production in the form of renewable energy sources are expected to increase in the coming years, a consequence of this is instability of the power grids due to the stochastic nature and lack of inertia of renewable energy sources. In addition, small and local, so called island grids, are on the rise and these system may present an even higher sensitivity to frequency fluctuations. READ MORE
