1. 6. Evaporation Duct Modelling for a Wave-Propagation Simulator

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : Oscar Eklund; [2022]
   Keywords : evaporation; duct; height; monin; obukhov; mos; surface; layer; ssft; byc; pj; businger; dyer; beljaars; holtslag; cheng; brutsaert; sheba;

   Abstract : Long-range communication proves to be a challenge due to the Earth’s curvature, since electromagnetic waves propagate away from the Earth’s surface in a free atmosphere. A possible solution to beyond line-of-sight communication is the atmospheric phenomenon known as the evaporation duct. READ MORE

3. 7. Development of a Method to Predict the Adhesion of Industrial Paint Coating

   University essay from KTH/Fiber- och polymerteknologi

   Author : Akheen Sadik; [2022]
   Keywords : Contact angle technique; optical tensiometer; paint coating; adhesion promoter; silane; kontaktvinkel; optisk tensiometer; ytbehandling; adhesion; silan;

   Abstract : I samarbete med Sherwin-Williams AB, utvecklades en metod med kontaktvinkelmätning för att teoretiskt uppskatta vätbarhet och vidhäftningsförmåga av industriella färger på stålsubstrat. Optisk tensiometer och Youngs ekvation kombinerat med OWRK beräkningsmodell användes för att bestämma ytenergier. READ MORE

4. 8. ManagementPractical Aspects of Aqua Ammonia as Secondary Refrigerant in Ice Rinks

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Jacqueline Pierri; [2021]
   Keywords : Ice rink; secondary refrigerant; refrigeration; refrigerant management; secondary fluid; natural refrigerant; aqua ammonia;

   Abstract : The transition from fluorinated gases to natural refrigerants could be key to reducing the impacts of climate change. Ice rinks are energy-intensive buildings, with large heating and cooling demands. The pumping power required to move the secondary refrigerant typically accounts for a sizable amount of the energy use of the refrigeration system. READ MORE

5. 9. Terracotta Vessels : Food storage addressing global challenges

   University essay from Konstfack/Industridesign

   Author : Malin Björklund; [2021]
   Keywords : food waste; design; sustainability; industrial design; product design; terracotta; clay; food storage; global goals; UN; food; concept design; green design; nudge; behaviour; evaporative cooling; evaporation; emotional durable design; zeer pot; pot-in-pot cooler; refrigerator; fridge; appliances; low tech; ceramics; hållbarhet; design; industridesign; produktdesign; grön design; terrakotta; keramik; vitvaror; matförvaring; globala målen; FN; matsvinn; mat; avdunstning; konceptdesign; beteendemönster;

   Abstract : Terracotta vessels are about understanding how we can store food by using a new product solution and how we could use less energy and waste less food in doing so. This project is an attempt to minimise the energy usage in our homes but also to gain greater understanding about the food we choose to bring into our homes and what we can do to avoid throwing it away.

6. 10. Nedkylning av urbana miljöer genom landskapsarkitektur : ett temperatursänkande gestaltningsförslag för ett industriområde i Stockholm

   University essay from SLU/Dept. of Urban and Rural Development

   Author : Ulrika Liljenfeldt; [2020]
   Keywords : landskapsarkitektur; hållbarhet; nedkylning; värmeöeffekt;

   Abstract : Förtätning och eliminering av grönska i våra städer orsakar idag stora problem med värme i urbana miljöer. Då ett varmare klimat är att vänta kan problemen med värme väntas bli ännu allvarligare i framtiden. Ju högre temperaturen är i den kringliggande luften desto högre blir belastningen på byggnadernas kylsystem. READ MORE
