Dynamic loads on Francis turbines
, 2016 New installations of unregulated power to the electrical grid have led to more fluctuations in the grid frequency. Hydropower plants with large reservoirs can provide services to balance the frequency by increasing or reducing production in accordance to what is needed.

FSI-analysis of a Francis turbine
, 2012 Sediment erosion in Francis turbines is a big problem in hydropower plants in and around the Himalayas. The sediment composition in the rivers contains high levels of the hard mineral quarts. When the sediments enter the turbine they cause erosive damage to exposed parts such as covers, guide vanes and runner.

Dynamic Analysis of a Francis Turbine
, 2019 Francisturbiner er velkjente installasjoner i norske vannkraftverk. De dynamiske egenskapene til en Francisturbin påvirkes signifikant av miljøet den opererer i, det er derfor et stort ønske å forstå samspillet mellom turbin og vann bedre for å sikre stabil kraftproduksjon.
