Hello there-

Great forum you have here!

Does droplet size adhere to the law of diminishing returns?

Apparently the current industry standard of 160-200 psi with a properly designed nozzle without compressed air aeration atomization will result in 44-60 VMD micron size.

I also know that the evaporation rate is inversely proportional to the square of the diameter of the droplet.

Sooo... considering that you would prefer the evaporation to occur in the cylinder and not the compressor outlet would an equal sized water mass of 11 micron droplets which would evaporate 16 times faster than the 44 micron sample be advantageous or not? What about the alternative of a 176 micron droplet that would evaporate 16 times more slowly giving the water mass more time to achieve maximal cooling in the cylinder?

The reason I ask is that some system designs are using 15 psi of boost pressure alone while some of the big diesel setups are using 1000 psi.

Thanks for your thoughts!
