1. 1. Test rig for evaluation of protective coating against molten aluminum

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Sashank Ghandikota; [2023]
   Nyckelord :TES; PCM; protective coating; thermal energy storage; TES; PCM; skyddande beläggning; lagring av värmeenergi;

   Sammanfattning : Today, many methods test the lifetime of coatings, but none focus on testing protective coatingsin a non-oxidizing environment. Hence, this master thesis developed a method to test the life-time of a protective coating against molten aluminum. LÄS MER

   Sammanfattning : This thesis explores the heat transfer characteristics of a packed bed thermal energy storage device through the development of a 3D model in COMSOL Multiphysics. The model is based on a laboratory-scale device consisting of an aluminum box filled with sand, which acts as the thermal storage medium. LÄS MER

4. 3. Comparing the Effects of Flexibility Options on Conventional and Low-temperature District Heating Networks : Studying the potential of the next generation of district energy systems

   Master-uppsats, KTH/Energiteknik

   Författare :Mario Nithyanathan; [2022]
   Nyckelord :District heating DH ; low-temperature district heating LTDH ; 4GDH; Flexibility; Thermal energy storage TES ; Optimization; Modelling; Fjärrvärme; Låg-temperatur fjärrvärme; 4GDH; Flexibilitet; Termisk energilagring TES ; Optimering; Modellering;

   Sammanfattning : District heating (DH) systems have been commonplace in Europe for over a century. These systems have undergone an evolution since their conceiving, and today we are at the precipice of the next major transition from the third-generation district heating system (3GDH) to the fourth generation (4GDH).

5. 4. Waste heat recovery systems : Fuel energy utilisation for a marine defence platform

   Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Författare :Filip Gustafsson; [2020]
   Nyckelord :Waste heat; Efficiency; Energy; Thermal energy storage; Marine; Restvärme; Verkningsgrad; Energi; Termisk energilagring; Marin;

   Sammanfattning : This report is a thesis for BTH in collaboration with the company Saab Kockums AB. In order to meet future environmental and economical demands, a vessel must reduce its fuel consumption to have a smaller climate impact and save money. LÄS MER

7. 5. A case study of the reduction of district heating energy consumption in a residential building in Örebro (Sweden)

   Master-uppsats, KTH/Energiteknik

   Författare :Laura PEREZ CASADO; [2018]
   Nyckelord :;

   Sammanfattning : One of the major challenges to be faced in the energy supply sector is related to the requirement of matching the demand side. This is especially the case for the countries characterized by a high share of renewable energy sources. Among the renewable energy sources the use of wind power and photovoltaics has a priority.
