1. 1. High-Temperature Thermal Energy Storage for Innovative Hybrid CSP/PV Plants : A Comprehensive Design Optimization

   University essay from KTH/Energiteknik

   Author : Lorenzo Centonze; [2023]
   Keywords : ;

   Abstract : By means of a literature review, critical parameters in the context of thermal energy storage systems, particularly packed bed thermal energy storage systems are identified. The goals of this thesis project are to come up with an optimized design for a PBSTES and to evaluate the thermal performance of alternative storage materials derived from byproducts of industrial processes and natural rocks in order to reduce the environmental impact of the designed system.

3. 2. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Ahsan Ali; [2023]
   Keywords : High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

   Abstract : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

4. 3. High Temperature Tribology of Exhaust Components in Alternative Fuel Engines

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Muhammad Hashir Zaheer; [2023]
   Keywords : High temperature tribology; Wear; Friction; Exhaust manifold; Lip seal ring; Wear resistant coatings; Inconel 718c; SiMo51 ductile cast iron; AlTiN; Tribaloy 400;

   Abstract : Internal Combustion Engine (ICE) exhaust components are exposed to extreme operating temperatures. Thus, it is necessary that they are designed with materials that can sustain thermal and vibrational stresses. READ MORE

5. 4. Microstructural design and optimization of Nickel-based superalloys for gas turbines

   University essay from KTH/Materialvetenskap

   Author : Anirudh Vasishta; [2023]
   Keywords : Nickel- based superalloys; gamma prime γ′ size calculations; Nickelbaserade superlegeringar; gamma prime γ′ storleksberäkningar;

   Abstract : One of the main sources of energy in this modern world is the gas turbine.  They reach extremely high working temperatures at peak capacity and hence require materials that can withstand the same. READ MORE

6. 5. Theoretical investigation of Co-dependence in magnetic high-entropy alloys

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Johan-Michael Kurak; [2023]
   Keywords : ;

   Abstract : High-entropy alloys (HEA) is a class of materials consisting of multiple principal elements that often crystallize in simple lattices such as body-centered cubic, face-centered cubic and hexagonal close-packed structures. Many HEAsexhibit exceptional mechanical properties, e.g. READ MORE
