16. Cavitation analysis on test rig. : An experimental and CFD study executed in collaboration with Epiroc AB
Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronikSammanfattning : This master thesis project was done in collaboration with Epiroc Group Ab. Epiroc supplies high-quality drills of various types that can be used both above and below ground. A major problem in their percussive rock drills is that that cavitation is formed. Cavitation is a phenomenon that occurs when a fluid is subject to a sudden pressure drop. LÄS MER
17. Vad gör en växt torktålig? : fysiologiska och morfologiska egenskaper i blad och rötter anpassade för en urban ståndort
Kandidat-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)Sammanfattning : The aim of this literature study is to examine and collect available information about physiological and morphological drought strategies and traits in woody species. Furthermore, the intention is to, based on collected information, discuss how this knowledge can be applied to the use of woody plant species in urban environments. LÄS MER
18. Numerical Study on Air Demand of Free Surface Flows in a Discharge Tunnel
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : Aeration issued through a ventilation shaft is an important measure to prevent cavitation and large gauge pressure in flood discharge tunnels. In order to dimension the ventilation shaft appropriately, itis necessary to have a good understanding of the air-water flow in the tunnel. LÄS MER
19. Design- och simuleringsstudie av flödeshus och sensorkropp
M1-uppsats, KTH/Hållbar produktionsutveckling (ML)Sammanfattning : I detta arbete har ett koncept utvecklats för en flödesmätningsmetod med en intern sensorkropp samt bibehållen flödeshastighet. Denna mätmetod består av en sensorkropp i ett flödeshus där mätningen av flödet utförs med hjälp av pitotrörsberäkningar. LÄS MER
20. Aeration and risk mitigation for flood discharge tunnel in Zipingpu water conservancy project
Master-uppsats, KTH/BetongbyggnadSammanfattning : The importance of hydraulic structures has become an essential mitigating mean for floodsthat occur more often due to climate change. Thus, the importance and safety of flooddischarge tunnels has promoted further studies and experiments on the topic to mitigatedamages, such as cavitation that arise because of high speed flows.
