Recommendations
Based on the results of this literature review, there are significant gaps in research
that may be important to Reclamation as well as the hydropower industry. These
include;
1. A study to determine the loss of turbine efficiency when a vortex is
present.
2. A study to determine the loss of turbine efficiency when a vortex
suppression device is install to reduce the formation of a vortex.
3. A study that will perform a full inventory of Reclamation facilities (both
hydropower and non-hydropower) to determine occurrence of vortex
formation, and if vortex suppression is advised.
