The link is in the original quote from Larry. Looking back it is sort of hidden so
this time I put it in bold. David I'm very interested in your opinion on this, it ties
directly into some of the the R&D work I'm currently involved with.
Schlieren combustion
Quote:
"This video of combustion taken at 10,000 frames per second, with the
Photron Ultima APX-RS camera Schlieren photography records density
differences so you can clearly see the high temperature areas generated
by combustion process. Schlieren photography only sees changes in density,
much like you see mirage and heat waves on a hot highway. All you can
say with certainty is that the area just above the piston crown is distinctly
different in local density than the fuel air mix a centimeter or so above the
piston crown."
"That said my guess is that the activity that we see in that clip is heat transfer
by conduction from the hot piston crown to the relatively cooler fuel air mix."
