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

   Master-uppsats, KTH/Energiteknik

   Författare :Lorenzo Centonze; [2023]
   Nyckelord :;

   Sammanfattning : 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. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Nipon Roy; [2023]
   Nyckelord :Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

   Sammanfattning : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. LÄS MER

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap; Uppsala universitet/Byggteknik och byggd miljö

   Författare :Joakim Nyberg; [2023]
   Nyckelord :comsol; finite element method; multiphysics; multiphysics simulation; PDE; DE; FEM; 4GDH; governing equations; simulering; comsol; vattenburen golvvärme; golvvärme; FEM; finita elementmetoden; PDE; partiella differentialekvationer; fjärde generationens fjärrvärme; 4GFV; EAS; värmesimulering;

   Sammanfattning : This report formulates the boundary conditions and discretization method for conducting a simulation of heat with liquids and solids through the finite element method. It introduces the reader to the movement that is due today with optimization of heat transport and mitigation generally described as the fourth generation of district heating. LÄS MER

5. 4. Deep Neural Networks as SurrogateModels for Fuel Performance Codes

   Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

   Författare :Wenhan Zhou; [2023]
   Nyckelord :Transuranus; AI; Nuclear Fuel Rods;

   Sammanfattning : The core component of a nuclear power plant is the reactor and the fuel rods that supply it with fission fuel. Efficient and safe energy extraction is thus highly dependent on the reactor design and the conditions of the fuel rods. To anticipate high-quality operation and potential risks in advance, one must perform simulations on the fuel rods. LÄS MER

7. 5. Small-scale wave energy converter for wave tank facility

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

   Författare :Samir Asseh; [2023]
   Nyckelord :Wave power; small-scale; Wave tank; facility; Renewable resources; damping; froude scaling; magnets; copper coil; Uppsala University; buoy; MATLAB; COMSOL; PTO; WEC; Electricicity generation.; Förnybar energi; Vågtank; Vågkraft;

   Sammanfattning : A small-scale wave energy converter was designed and built for teaching and academic purposes to be used at The Division for Electricity, in the Ångström Laboratory at Uppsala University. The design of the power take-off (PTO) makes use of magnets passing through a copper coil for electricity generation. LÄS MER
