1. 16. Framtagning av principkonstruktion för reglering av luftflöden inom ventilation

   M1-uppsats, Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

   Författare :Joakim Grönberg; Fredrik Hansson; [2023]
   Nyckelord :Ventilation; CFD; Exhaust hood; Ventilation; CFD; Avluftshuvar;

   Sammanfattning : Takmonterade avluftshuvar kan ha ett krav att kastlängden av luftflödet ska överstiga en minimal höjd över takytan. Moderna ventilationssystem av typen VAV (Variable Air Volume) kan anpassa luftflödet till olika rum beroende på antalet personer och mätvärden på luftkvalitet i rummen, vilket kan leda till ett lägre luftflöde under nätter och helger.

3. 17. Validering av FDS för simulering av mindre vätgasläckage inomhus

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Emil Hamnes Alavei; Erik Andersson; [2023]
   Nyckelord :Hydrogen; Helium; Ventilation; CFD; FDS; Technology and Engineering;

   Sammanfattning : The prevailing global climate transition is incentivized to occur in a short period of time. Hydrogen is considered a pivotal element towards a renewable energy system. However, the physical and chemical properties of hydrogen give rise to the risk of fire and explosion. LÄS MER

4. 18. Development of CAD Models for Large Silencer Platforms Using Design Automation

   Master-uppsats, Linköpings universitet/Produktrealisering

   Författare :Mahim Kai; Balagangadar Thilakar Arumugam; [2023]
   Nyckelord :Design Automation; Silencer; CFD; Extraction;

   Sammanfattning : Scania is known as a front-runner in the development of power trains for heavy vehicles, marine, and general industrial applications. As the regulations on emissions for combustion engine vehicles are getting tougher with increasing awareness on sustainable solutions and reducing environmental impact, the goal at Scania is to develop combustion engines to achieve low-pollutant emissions whilst achieving higher efficiency.

5. 19. #DeGenderFashion : A Visual Analysis of How Fashion Is Used to Challenge Gender Norms and Heteronormative Expectations

   Magister-uppsats, Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)

   Författare :Alexandra Edelsbrunner; [2023]
   Nyckelord :Fashion Theory; Gender Theory; Social Media Activism; Identity; Cultural Studies; Gender Norms;

   Sammanfattning : The study aims to answer the question of whether fashion can communicate meaning, by addressing how creators on Instagram challenge dominant gender norms through fashion, with a focus on the activist movement of #DeGenderFashion. The research questions will be answered using fashion theory and gender theory as guiding points, with literature on social media activism, representations of gender, and cultural studies giving further insight into the dynamics of the movement.

7. 20. Study of mixing and exchange in a drinking water reservoir using CFD modeling

   Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

   Författare :Nadja Rabizadeh; [2023]
   Nyckelord :CFD; Fluid Mechanics; OpenFOAM; drinking water reservoir; URANS; transient; exchange of water; mixing; Norrvatten;

   Sammanfattning : This thesis examines water mixing and exchange in a drinking water reservoir operated by themunicipal association Norrvatten. Recent water samples from the reservoir’s outgoing waterhave shown an increase in culturable bacteria during late summer and fall. LÄS MER
