Denne masteroppgaven fokuserer på design og analyse av en komplett Francis turbin for Framo AS med formål om energiutvinning i offshore-applikasjoner. Turbindesignet skiller seg fra konvensjonelt design ved at den ikke har ...

Sediment erosion is a large problem for turbines operated in sand laden water, especially in the Himalayas and the Andes Mountains, where the contents of hard minerals in the rivers are high. A program called RenewableNepal ...

Finding new energy sources to provide base load electricity supply on a global scale is of increasing importance. Enhanced Geothermal Systems (EGS) has been identified as capable of playing an important role in the future ...

Hydraulic modeling is a useful tool to analyze the impacts from changes in the flow and in the morphology of a river. To achieve accurate results it is necessary to collect detailed data of the topography of the area, ...

Winter-runoff from airports contains a high fraction of contaminated stormwater. Contaminants such as de-icing chemicals propylene glycol and potassium formate, heavy metals and PAHs are often present in stormwater runoff ...

Physical models are a well-accepted tool in hydraulic engineering, allowing for the detailed characterisation of flow processes and the validation of structure designs with complex boundary conditions. The methods used to ...

Military and civil installations can be equipped with a granular filter, for example in air inlet systems to protect against blast waves. Granular filters also have a certain potential to replace shock valves and to work ...

The design and results from a hydraulic scale model of mass oscillations in a hydropower plant with a closed surge tank constructed as an underground rock cavern are presented. The results from the model test of an existing ...
