4. 3. Suppression of Li-ion Battery Fires

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Linfan Cai; [2023]
   Nyckelord :Lithium-ion Battery; Fire Suppression System; Extinguishing Agent; Thermal Runaway; Battery Energy Storage System; Electric Vehicle; Technology and Engineering;

   Sammanfattning : This thesis presents a systematic literature review of fixed fire suppression systems and extinguishing agents for lithium-ion battery (LIB) fires. The review identifies 85 relevant sources published between 2013 and March 2023, and categorises different research experiments into cell-level, module-level, electric vehicle (EV) pack-level, battery energy storage system (BESS) rack-level and warehouse storage experiments, according to LIB configurations.

   Sammanfattning : Energy efficiency and reduced energy consumption are two highly discussed topics in the global environmental debate where Sweden as a country is at the forefront. High demands on streamlining energy usage exists where a goal is to by 2030 have a 50% more efficient energy use than in 2005. LÄS MER

7. 5. Oil Autonomy of a Turbojet

   Master-uppsats, KTH/Flygdynamik

   Författare :Florian Steiner; [2022]
   Nyckelord :Fluid Mechanics; Turbojet; Oil circuit; Fluid Mekanik; Turbojet; Oljekrets;

   Sammanfattning : The oil circuit of a jet engine is required to lubricate and cool mechanical parts. The oil is pumped from the oil tank and flows through heat exchangers. Then it is injected on the bearings for lubrication and cooling, before being scavenged at the bottom of the sumps and finally flows back to the oil tank. LÄS MER
