1. 11. External Heat Transfer Coefficient Predictions on a Transonic Turbine Nozzle Guide Vane Using Computational Fluid Dynamics

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Daniel Enico; [2021]
   Keywords : CFD; LS89; transonic turbine; transition; transition model; turbulence decay; turbulence intensity; length scale; turbulence characteristics; HTC; external heat transfer coefficient; Steelant-Dick postulation;

   Abstract : The high turbine inlet temperature of modern gas turbines poses a challenge to the material used in the turbine blading of the primary stages. Mechanical failure mechanisms are more pronounced at these high temperatures, setting the lifetime of the blade. READ MORE

3. 12. Aerothermal and Kinetic Modelling of a Gas Turbine Dry Low Emission Combustion System

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : David Håkansson; [2021]
   Keywords : Gas turbine; combustion; one-dimensional combustion simulation; network model; general network model; NOx emissions; hydrogen; Gasturbin; förbränning; endimensionell förbränningssimulering; nätverksmodell; generell nätverksmodell; NOx-utsläpp; väte;

   Abstract : Growing environmental concerns are causing a large transformation within the energy industry. Within the gas turbine industry, there is a large drive to develop improved modern dry-low emission combustion systems. The aim is to enable gas turbines to run on green fuels like hydrogen, while still keeping emission as NOx down. READ MORE

4. 13. 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

5. 14. EXPERIMENTAL STUDY ON PRESSURE LOSSES IN ADDITIVELY MANUFACTURED AND MACHINED ORIFICES : A rectangular geometry of additively manufactured MA 247 orice and a circular geometry ofmachined AW-6082 T6 orifice study

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Jayadev Nambisan; [2020]
   Keywords : Cooling; Fluid Dynamics; Additive Manufacturing; Pressure Losses; Fluid Dynamics Testing; Machining; Gas Turbines; Gas Turbine Cooling; Nouveau Geometries;

   Abstract : Gas turbine components for cooling purposes including other unique and complex three-dimensional designs could be made explicitly possible through additive manufacturing using SLM technology in contrary to the conventional machining processes. Nevertheless, the surface roughness and subsequently the friction factor governs thepressure drop in these components implicitly, thus, influencing the secondary air flow system of a gas turbine.

6. 15. CAE of Gas Turbine Combustor Chamber : Improving workflow in product lifecycle management systems

   University essay from Linköpings universitet/Maskinkonstruktion

   Author : Jakob Söderberg; [2020]
   Keywords : Product Lifecycle Management; Computer Aided Design; Computer Aided Engineering;

   Abstract : This thesis seeks to improve the workflow in the product development process when using the Product Lifecycle Management (PLM) system PLM2020, incorporated at Siemens Energy. Focus is on three problem cases that emerge when working with Computer Aided Engineering (CAE) data during the development process. READ MORE
