Analysis on cause of erosion of guide vane of high‐head Francis turbine in sandy river
Energy Science & EngineeringThe Kizilsu River Basin in China is located in the desert Gobi area with high sediment content and high hardness. After 4798h operation, the maintenance of a high‐head Francis turbine in this basin found that the guide vane was seriously worn, and even ...

Steady Flow Analysis of Francis Turbine
Journal of Mechanical Engineering, 2009 The flow features are presented on different openings in Francis turbine by unsteady numerical simulation. The unsteady flow results are as follows:when the opening is 12 mm, pressure fluctuation at runner outlet near hub is not obvious and pressure fluctuation amplitudes near midstream and shroud are bigger.

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.
