EXP 1-1 Introduction

Spray formation

The produced droplets cover a wide size range and form a single or double-peak size distribution (in Figure 2b), depending on the position in the spray. The droplets with $dD<20\mu m$ fast decelerate to the airflow velocity, medium-size droplets $(20\mu m<dD<50\mu m)$ feature a positive size–velocity correlation, and the largest droplets up to 100 µm keep the original velocity of the discharged liquid. The smallest droplets follow the local air velocity closely, and so the velocity of droplets sized below 5 µm can serve as the air velocity estimate.
