Atomizer used for experiment
Experimental setup
Malvern Spraytec Analyzer
- Working principle: Fraunhofer diffraction; line-of-sight measurement.
- Purging air is supplied at the transmitter and receiver ends to ensure dust-free collection of data, leading to reduction of errors.
- A 670 nm LASER beam from the transmitter to receiver end (containing rings), undergoes scattering when interrupted by spray particles.
- Droplet diameters (1 to 1000 µm) are determined based on the optical scattering pattern observed at the receiver end.
