Cavitation
This category depends on selecting the Unit Power Table method, (see “Unit Power Table”), and contains methods for dealing with the problem of cavitation on turbines. Cavitation is the sudden formation and collapse of low-pressure bubbles in liquids by means of mechanical forces, and this process can cause damage to turbines under certain operating conditions.
* None
This is the default, no action method.
* Unit Head and Tailwater Based Regions
This method allows the user to specify the regions of operation in which cavitation does not occur, so these regions can be avoided. These regions can be dependent on both operating head and tailwater.
See “Unit-level Constraints” for details about added constraints.
