Effect of atomizing air flow on spray atomization of aninternal-mix twin-fluid atomizer

The effect of the atomization air flow rate on the spray characteristics of a swirling twin-fluid atomizer operating on Diesel fuel is investigated. The mean droplet axial velocity and size distributions were simultaneously measured using a phase Doppler anemometer (PDA). The mean droplet diameter i...

description The effect of the atomization air flow rate on the spray characteristics of a swirling twin-fluid atomizer operating on Diesel fuel is investigated.
