1. Effekter av packning av finfilter i fyllningsdammar
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : There are over 10 000 dams in Sweden of various types and sizes. Most of the larger dams were built around 1950-1970 when the Swedish hydropower was expanded. Since then, the knowledge of engineering dam structures has increased and there are new guidelines for how a dam should be built. LÄS MER
2. Shallow Water : A comparison between hydraulic measurements and numerical models
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : In the near future hydropower will be used to regulate intermittent energy sources, shallow water ways can then occur in close proximity to the power plants, where the bottom often consists of stones in a similar length scale as the water depth. The idea of this project, which has been initiated by Vattenfall R\&D, is to compare experimental measurements in a laboratory environment with numerical simulations with CFD, this to find a way to represent roughness structures where there is low relative submergence.

3. Manning’s roughness coefficient in small scale nature-like fish passages
Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresursläraSammanfattning : Fishway construction remains a crucial measure in environmental adaption of flow barriers. A well-functioning fishway should be able to pass all naturally occurring species of fish and other aquatic fauna. LÄS MER
4. Rotor Dynamic Modeling of Hydropower Rotors by 3D-Finite Element Analysis
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : By using the rotor dynamic capabilities of Simcenter Nastran Rotordynamics, an eigenvalue analysis of 3D-finite element models of the Jeffcott rotor and the overhung rotor were conducted and compared to the results with beam-based, lumped parameter models. The first two critical speeds of the Jeffcott rotor were estimated with variations of 3. LÄS MER
5. Architecture of Power
Uppsats för yrkesexamina på avancerad nivå, KTH/ArkitekturSammanfattning : The 34 silos at Jarlaberg today contain crude oil but after the lease of land expires at 2036 are refurbished and remade to hold 2 500 000 m3 of water from Stockholm archipelago. Sharing the industrial plot of the reworked silos are 13 buildings with 2000 households between them. LÄS MER
