Aeration vs cavitation

Web2.7K views 4 years ago Cavitation has the potential to cause the degradation failure of the entire hydraulic system. It is also the common cause of catastrophic pump failure. Show more Show more WebThere is the potential for cavitation damage when the cavitation index, σ. is between 0.2 and 0.5, for typical concrete. For large features that are introduced into the flow abruptly (such as stilling basin baffle blocks or splitter walls), cavitation damage can occur when the σ is as high as 1.0 or greater.
