Each of the 38 .csv file in this folder is associated with a different working condition of the nozzle. 
Specifically, the name 'alpha##_Re##_We##.csv' contains the working condition of the nozzle as
- alpha## (## is the spray angle)
- Re## (## is the Reynolds number)
- We## (## is the Weber number)
 
Each file contains as many raws as the number of drops.
In the i-th raw, 
1) the first element is the Volume of the i-th drop;
2) the second element is the estimated surface of the i-th drop with the method in equation (18) of [1];
3) the third element is the equivalent diameter of the i-th drop (i.e., as if it was spherical - computed from the volume)
