The spray measurement with two different optical methods

Popis výsledku v původním jazyce

The aim of the paper is to compare two optical measurement methods for the measurement of the atomization properties of the two-phase nozzle. The measured liquid is the water at a room temperature and the atomization fluid is the compressed air. The first method is the Phase Doppler Anemometer (PDA) and the second is the Laser Diffraction LD. The two commercial instruments were tested, together with inhouse photogrammetric measurement of the nozzle outlet. The tested droplets have Sauter Mean Diameter approximately around 10 µm. The presented results could be useful for the estimation of the advantages and disadvantages of the methods and recommend the application in the wide field of aerosol technology. The first results of the comparison show the fine resolution with PDA system, but the tuning of the setup requires several times more time. The accuracy of the LD is sufficient. The important advantage of the PDA system is knowledge of the velocity distribution for each measured droplet.
