1. 11. Modelling the full-scale N2O emissions from wastewater treatment plants for identifying mitigation strategies

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Naga Deepika Peddamudium; [2023]
   Nyckelord :Modelling; simulation; ASM2dISS; N2O production pathways; N2O emission factor; mitigation strategies; water and environmental engineering; Technology and Engineering;

   Sammanfattning : Nitrous oxide (N2O) emissions, which primarily originate from the biological nitrogen removal process, dominate the release of greenhouse gases (GHGs) in wastewater treatment plants (WWTPs). N2O production occurs through dynamic microbial pathways that have a significant impact on the environment compared with other GHG emissions. LÄS MER

3. 12. Modelling Gas Flow Behaviour in Gas Atomizer

   Master-uppsats, KTH/Materialvetenskap

   Författare :Aravind Senan Vasanthasenan Reji; [2022]
   Nyckelord :Gas atomization; Nozzle; Velocity; Static pressure; Discrete phase model; Gasatomisering; Munstycke; Hastighet; Statiskt tryck; Diskret fasmodell;

   Sammanfattning : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.

4. 13. Numerical and experimental investigation of multiple gas jet flow behaviour in the gas atomization process

   Master-uppsats, KTH/Materialvetenskap

   Författare :Mahsa Darvishghanbar; [2022]
   Nyckelord :;

   Sammanfattning : In several industrial applications, the interaction of supersonic gas jets is encountered such as gas atomization, jet engines and the basic oxygen furnace process. In the gas atomization process, high pressure gases are converted to high velocity gas jets through convergent-divergent nozzles. LÄS MER

5. 14. Improvement of the 1D CFD method for Thermal management of a Battery Electric Vehicle

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :SASHWAT CHHETRI; [2022]
   Nyckelord :CFD; Electromobility; BEV; Thermal Management; Simulation;

   Sammanfattning : Electrification of vehicles is necessary to combat greenhouse gas emissions, whichcauses global warming and climate change. There has been a demand in the use ofBattery Electric Vehicles due to this increased awareness of sustainability. However,they have been beset with issues such as range and conservation of energy.
