1. 1. Flash Pulse Thermography Measurements of Coat Thickness

   University essay from Umeå universitet/Institutionen för fysik

   Author : Alexander Häggkvist; [2023]
   Keywords : Flash Pulse Thermography; Power Function; Dynamical Thermal Tomography;

   Abstract : The application of varnish, metal coats, and paint is a common practice for modifying or enhancing material properties. Metal coats are frequently used as protective layers against corrosion, heat, and wear, while also influencing characteristics like conductivity, weight, and production costs. READ MORE

3. 2. ENVIRONMENTAL AND ECONOMIC IMPACT OF USING RECYCLED MATERIALS IN WALL INSULATION : Energy management for sustainable cities, ETC building project.

   University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Author : Karima Alothman alsaghir; [2023]
   Keywords : Residual buildings; Walls insulation; Recycled materials; Thermal conductivity; IDAICE software; Climate-smart building; Thermo-environmental assessment; Thermo-economic assessment.;

   Abstract : Recycled material has attracted extensive interest due to its positive impact on decarbonization in the building sector. At the same time, utilizing these materials is limited. The main objective of this degree project is to provide a better understanding of recycled materials and their role in environmental and economic aspects.

4. 3. WEAR RESISTANT MULTI FUNCTIONAL POLYMER COATINGS

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

   Author : Pranay Kumar Parsi; [2023]
   Keywords : Polymer coatings; Materials; Tribology; Wear resistant; Ice adhesion; Freezing delay; Anti-icing de-icing;

   Abstract : This study aims to develop coatings which show wear resistant behaviour along with multiple functions such as improved ice adhesion, better freezing delay etc which help in improving the effectiveness of the wind turbine efficiency. The significance of anti-icing/de-icing solutions for wind turbines is emphasized since ice accretion can cause serious issues in generation of power and might lead to damage of blades. READ MORE

5. 4. Calibration of the Measurement System for Methane Pyrolysis in Rocket Nozzle Cooling Channels

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Jennifer Ly; [2023]
   Keywords : Correlational method; gas analysis; real time measurements; speed of sound; thermal conductivity; methane pyrolysis; rocket nozzle cooling; Korrelationsmetod; gasanalys; mätningar i real tid; ljudhastighet; värmeledningsförmåga; metanpyrolys; kylning av raketmunstycken iv;

   Abstract : Methane-based rocket propellant is gaining traction as a green technology with advantages in sustainability, cost-effectiveness, and performance. However, under high temperatures found in rocket nozzle cooling channels, methane can undergo thermal decomposition known as methane pyrolysis, resulting in the generation of hydrogen and solid carbon.

6. 5. First principles investigation of the thermal conductivity of Zr, ZrC, and ZrN

   University essay from KTH/Fysik

   Author : Daniel Karlsson; [2023]
   Keywords : Electron-phonon interaction; Density functional theory; Boltzmann transport equation; first-principles; thermal conductivity; electrical resistivity; Abinit; Phono3py; Elektron-fononväxelverkan; täthetsfunktionalteori; Boltzmanns transportekvation; värmeledningsförmåga; elektrisk resistivitet; Abinit; Phono3py;

   Abstract : The thermal conductivity and electrical resistivity of Zr, ZrC, and ZrN were calculated using first-principles density functional theory (DFT) and the Boltzmann transport equation. The electron-phonon scattering was modeled via the self-energy relaxation time approximation (SERTA), and the phonon-phonon scattering via the analogous single-mode relaxation time approximation (SMRTA).
