1. 16. Mäta HRR från Li-jonbatterier med hjälp av OCC (oxygen consumption calometry) och andra metoder

   Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Olof Skyllberg; [2023]
   Nyckelord :Litium-jon batteri; Termisk rusning; Oxygen consumption calorimetry OCC ; Sensible enthalpy rise approach SERA ; effektutveckling. Lithium-ion batteries; Thermal runaway; Heat release rate.; Technology and Engineering;

   Sammanfattning : One of the most important parameters to measure in the fire discipline is the heat release rate (HRR). Therefore it is very important that these measurements are accurate and as correct as possible. The most common method for measuring heat release rate of fires is the OCC method (oxygen consumption calorimetry). LÄS MER

3. 17. Status Mapping of tank to grave management of Low-GWP refrigerants.

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

   Författare :Sandra Parra Gimeno; [2023]
   Nyckelord :Refrigerant; Blends; Synthetic low-GWP refrigerant; Natural refrigerant; Global Warming Potential GWP ; Tank-to-grave; Interviews.; Köldmedier; Blandning; Globalt uppvärmningspotential GWP ; Låg-GWP köldmedier; Naturligt köldmedier; installation till destruktion; Intervjuer.;

   Sammanfattning : Refrigeration plays a vital role today in various residential, commercial, and industrial processes, requiring refrigerants to facilitate the cooling or heating processes. Over time, refrigerants have undergone significant changes to meet technological, social, environmental, and economic needs. LÄS MER

4. 18. Wildfire growth modelling in Sweden - a suitability assessment of available data

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Henrik Hagelin; [2023]
   Nyckelord :Geography; GIS; Geographic Information Science; Physical geography; Prometheus; WiSE-FASS; The 2014 Västmanland wildfire; Wildfire growth modelling; Wildfire suppression support; Wildfire behaviour; MESAN; Earth and Environmental Sciences;

   Sammanfattning : Wildfires are worldwide problems that stress societies by damaging their economies and they cause serious, sometimes fatal, health implications among the populations. In recent years, the rate of wildfire occurrence has increased as the global average temperature has risen. Because of global climate change, this rate is expected to continue rising. LÄS MER

5. 19. Design, Analysis and Performance Evaluation of Indirect Solar Dryer

   Magister-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Tandin Jamtsho; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : Food production is a critical component of global livelihoods and economic revenue. However, storing harvested food presents challenges in minimizing post-harvest losses. Among various methods, food drying has emerged as a popular technique for preserving food during off-seasons. LÄS MER

7. 20. Conceptualisation, Implementation and Commissioning of a Controlled Pyrolysis Rig : KTH Master Thesis Report

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

   Författare :Arjun Monga; [2023]
   Nyckelord :coke deposition; pyrolysis; catalysis; methane; sample; cooling channels; regenerative cooling; rocket engines; koksavsättning; pyrolys; katalys; metan; prov; kylkanaler; regenerativ kylning; raketmotorer;

   Sammanfattning : Liquid methane has seen popular interest from industry and academia as a next-generation rocket fuel due to its favorable performance characteristics and potential for extra-terrestrial in-situ resource utilisation. Since the rocket combustion chamber and nozzle are subject to high heat loads, regenerative cooling is a standard method to achieve lower temperatures. LÄS MER
