Term: local efficiency of atomization, ɛa
https://doi.org/10.1351/goldbook.L03602

Definition:
The substance fraction of atomized component in the component consumed. The efficiency of atomization is measured in a given part of the flame, usually the observation space; ɛa = ɛn.χs.χv.χa. The signal is a function of the product q v ɛ a, but ɛa is also a function of q v, usually decreasing at high volume rates.
