Detailed Description

Impinging-jet drop size is NACA TN 4222 (Ingebo 1958), and it reproduces TN 4222's own data.

TN 4222 Table I: pairs of impinging n-heptane jets in an airstream (82 F, 29.3 in Hg). Columns:
jet velocity Vj [ft/s], airstream velocity Va [ft/s], orifice Dj [in], measured D30 [micron].
The fitted correlation is Dj/D30 = 2.64 (Dj Vj)^0.5 + 0.97 Dj dV. The function this replaced cited
the report but ran a different (crossflow, TN 4087) form and came out ~0.47x the measured size.
