1. 11. Future climate suitability of shade trees in cocoa agroforestry systems in West Africa and shade tree diversity’s impact on farm microclimate : A Minor Field Study

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Jonna Halonen; [2023]
   Nyckelord :species distribution modeling; cocoa agroforestry; shade trees; West Africa; microclimate; distributionsmodell; kakaoskogslantbruk; skuggträd; Västafrika; mikroklimat;

   Sammanfattning : Shade trees’ implementation into cocoa agroforestry systems in tropical West Africa has proven to have a high potential in increasing farm resilience and mitigating climate change. However, no studies have yet examined the potential future climate suitability for shade trees in the region, which is important when deciding which shade trees to implement. LÄS MER

3. 12. Mathematical Modeling and Simulation of Cryogenic Liquid Hydrogen Storage

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Gusten Zandler Andersson; [2023]
   Nyckelord :Modeling; Simulation; Liquid Hydrogen; Storage tank; Modelica; Chemical engineering; Technology and Engineering;

   Sammanfattning : Liquid hydrogen is an attractive alternative to fossil fuels in the aviation industry, but storing it both before and during flights introduces many challenges pertaining to the cryogenic liquid conditions required. Having reliable models to predict the dynamical behavior inside the storage tank is therefore of great interest. LÄS MER

4. 13. Investigation of fuel and water injection in gas turbine combustion : Evaluate the methodologies available in Star CCM+ for modeling of water injection in simplified combustor using liquid and gas fuels

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :Sanger Shinwari; [2023]
   Nyckelord :Diesel and Methane fuel combustion; FGM combustion model; Lagrangian multiphase modelling; Inert Stream; Water injection; STAR CCM ;

   Sammanfattning : The negative impact of gas turbine emissions on the environment and human health is a growing concern. Recent studies suggest injecting water into the combustion process effectively reduces emissions and increases power output. However, this approach presents new challenges that need to be thoroughly investigated. LÄS MER

5. 14. Hur kan framtidens energibehov säkerställas i asfaltbranschen? : En studie för att finna potentiella åtgärder som leder till ett minskat energibehov för ett asfaltverk, samt undersöka möjligheten att producera solel på en asfaltanläggning

   Master-uppsats, Linköpings universitet/Energisystem

   Författare :Stina Berglund; Tove Danielsen; [2023]
   Nyckelord :Asphalt plant; Energy audit; Energy efficiency; Renewable energy; Asfaltverk; Energikartläggning; Energieffektivisering; Förnybar energi;

   Sammanfattning : Ett scenario för att nå nettonollutsläpp av växthusgaser till år 2050 har tagits fram av IEA. I scenariot framgår att det krävs en ökning av energieffektivisering, samt att användning av förnybara energikällor bör öka under detta årtionde. LÄS MER

7. 15. Model Predictive Control for Ground Source Heat Pumps : Reducing cost while maintaining comfort

   Master-uppsats, Linköpings universitet/Reglerteknik

   Författare :Isak Bokne; Charlie Elf; [2023]
   Nyckelord :MPC; Model Predictive Control; heat pump control; electricity spot price; weather prediction; reducing cost;

   Sammanfattning : Today, the control of heat pumps aims to first and foremost maintain a comfortable indoor temperature. This is primarily done by deciding input power based on outside temperature. The cost of electricity, which can be rather volatile, is not taken into account. LÄS MER
