Experimental methodology to measure spray microscopic characteristics for real multi-hole nozzles

A complete methodology to obtain the spray microscopic characteristics of Diesel sprays has been developed. Previous knowledge of the CMT Motores Térmicos group allows the use of PDPA technique on isolated diesel sprays. The difficulty arises when there are five or more simultaneous sprays affecting all the optics of the laser.

A new masking device that allows to isolate one spray was developed together with Robert Bosch. This masking device together with good optical access allowed measuring the droplets diameter and velocity under equivalent engine conditions.

The methodology developed considers all the correction and calibration procedures to perform accurate measurements on the basis of the data taken. The more relevant results from the PDPA installation are:

- Sauter Mean Diameter.
- Droplet velocity.
