1. 16. Simulation of an Innovative Integrated Solar Receiver/Combustor Unit for Flexible Gas Turbine Based CSP

   Master-uppsats, KTH/Energiteknik

   Författare :Cristina Blajin; [2020]
   Nyckelord :;

   Sammanfattning : In the wake of climate change, the generation of renewable power is of vital importance to ensure a sustainable development with reduced carbon emissions. Among all renewable energy sources, solar power is the most abundant and has a great potential to move the global energy production away from fossil fuels as well as to bring power into regions that currently lack access to electricity.

3. 17. Model Adaptation of a Mixed Flow Turbofan Engine

   Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Oskar Lindkvist; [2020]
   Nyckelord :Turbofan engine; Gas turbine; Performance model; Component maps;

   Sammanfattning : Gas turbine performance models are usually created in an object oriented manner, where different standard components are connected to form the complete model. The characteristics of these components are often represented by component maps and empirical correlations. LÄS MER

4. 18. Simulation Study on Lifted Hydrogen and Methane Jet Flames in Hot Vitiated Coflow

   H-uppsats,

   Författare :Henrik Forsting; [2019-07-03]
   Nyckelord :Farkostteknik; Hållbar utveckling; Energiteknik; Energi; Vehicle Engineering; Sustainable Development; Energy Engineering; Energy;

   Sammanfattning : Combustion of fossil fuels is the most important energy source today. Burning fossil fuel is however expensive and bad for the enviroment. Improving the combustion technology to reduce fuel consumption, and to be able to burn renewable fuels is therefore of great importance. LÄS MER

5. 19. Modelling of a Generic Aircraft Environmental Control System in Modelica

   Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

   Författare :Sabin Poudel; [2019]
   Nyckelord :ECS; Environmental Control System; Modelica; Object oriented Modeling; TTECCS library; bootstrap system;

   Sammanfattning : This thesis documents the modelling of generic Environmental Control System(ECS) of an aircraft in Modelica by utilizing components from free version of theTTECCS (Technical Thermodynamic Environmental Control and Cooling Systems) library. In doing so, components used for developing ECS from the TTECCS library are mathematically verified with theoretical formula in MATLAB. LÄS MER

7. 20. Throughflow Study on Bleeding for Part Load Compressor Operation

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Simon Hedkvist; [2019]
   Nyckelord :Compressor; Minimum environmental load; Aerodynamic; Throughflow; Stability; Bleeding;

   Sammanfattning : The transition of the European energy grid to renewable energy sources is increasing the demand for back-up capacity with high flexibility. Current fossil fuel plants are continuously being forced into part load operation, where they are limited by pollution regulations that dictate their minimum environmental load, MEL. LÄS MER
