That's basically the Fogbuster design. It is a design that works well
but uses quite a bit of air. You lose most of the energy in the air by
regulating it down to a fairly low pressure before you feed it into the
tube.
That's why I went for my extended nozzle design that runs on ~100psi at
the nozzle, with a very small annular jet. A small amount of air leaves
the jet at high velocity and mixes with the surrounding air to produce a
lower velocity column of air at a high flow rate. The extended nozzle
injects coolant into the column at a point where it's velocity has
fallen low enough that it can't atomize the coolant.
By the way Gene, the Chinese misters I linked to previously to have two
tubes to the nozzle, one for air and one for coolant, so you don't get
any leakage at the lock line joints. That's how I manage to run mine at
high pressure.
