In 2010, a patent was issued to Kaijo Corporation (US 7,726,325) for a method to efficiently and rapidly “degas” liquids.  In short, the process involves passing a liquid through a restriction such as the narrowing of a pipe at a sufficient velocity that rarefication downstream from the restriction (ala Bernoulli’s principle) creates negative pressure to draw …

This discussion is a bit anecdotal in nature because my attempts to demonstrate the effects I describe in the following in the laboratory have been less than conclusive.  But, the fact that I have seen them occur on several occasions over a period of more than 50 years gives it a degree of credence.  By this time the …

I have talked about cavitation extensively in previous blogs.  But what I have neglected to address through an omission on my part is the fact that all cavitation does not produce the effect needed to enhance cleaning – namely, the catastrophic collapse of the cavitation bubble in implosion.  Before reading further, please take a minute …
