1. Flow and pressure measurements in low-head hydraulic turbines
Sammanfattning : Hydropower is a clean and sustainable energy resource that has been developed and used since the late 19th century. In Sweden, power plants have been constructed over the entire 20th century, with a peak in the period of 1950-1970. Currently, many of the older plants are in need of refurbishment. LÄS MER

3. Extension of the Pressure Time Method to 3-Dimensional Flows
Sammanfattning : Hydropower has stood as a clean and sustainable energy source since the late 19th century. Many turbines were built 50 to 70 years ago and require refurbishment. It is important to assess the efficiency of turbines before and after refurbishment to meet performance guarantees .However, the flow rate makes such estimation challenging. LÄS MER
