I think Jet Impingement is a Myth
Was adopted by Wcooling community in two ways.
Initially used for modeling the White Water when crudely applied Sieder-Tate gave inadequate h(conv) to explain results.
Was used as a "catch phrase" description and found to provide exciting visualisation for non-channel, in particular the Cascade series ,waterblocks. No numerical modeling was ever applied..
The crude modeling community (I) still use it , via Flomerics, as a convenient method of calculating h(conv) when L/d is < 60 .Even though, with the reduction of the accepted value of C/W[TIM](tester's TIM) from 0.1 to 0.06(10x10mm die), this is probably not necessary - adequate h(conv) can be obtained from Sieder-Tate by adjustment of the prefactor, outside the accepted 0.19-0.27 range, to account for "entry turbulation"
The non-modeling community still use, I guess , because it provides a pretty picture.
