Annular flow was achieved for ALR values between 0.1–0.7 (stable atomization).

At an ALR of 0.02, slug flow was predominant in 2 atomizers resulting in spray unsteadiness.

A low time-averaged x1,2 is not necessarily a predictor for a stable atomization process.

At all conditions oil drops were broken during atomization (min. x1,2; oil = 1.7 μm).
