“…Several reviews on this subject are available (see, for example, Wintderfeld et al [81], Lefebvre [24], Bachalo [166], Benjamin [167]). Presser et al [145,146] investigated the aerodynamic characteristics of a swirling spray flame using a pressure-jet atomizer. The effects of swirl on droplet transport, as well as the interactions between droplets and air flowfield, were studied under both non-reacting and reacting conditions.…”

“…Phase Doppler interferometry was employed by Presser et al to investigate the effect of swirl on droplet transportation in a pressure-atomized, hollow-cone kerosene spray in both burning and nonburning conditions. Their results showed that larger droplets are transported downstream relatively unperturbed by the surrounding air stream while smaller droplets are entrained by the recirculating aerodynamic pattern [18,19].…”

“…Aerodynamic characteristics of swirling spray flames in a pressure jet atomizer was investigated by Presser et al [5]. They reported that the introduction of swirl to the combustion air modified the droplet and air velocity field and the spatial distribution of droplet size and number density.…”

Combustors with fuel-spray atomizers are particularly susceptible to pressure or velocity oscillations resulting from the occurrence of thermoacoustic oscillations. Experimental investigations of distilled water spray -swirl -acoustic interactions are presented. The presence of a swirl flow field alters the behavior of water spray drastically. Investigations showed complex behavior of water sprays in an acoustic cycle. In the presence of acoustic oscillations the phase averaged droplet diameter variation with in an acoustic cycle is more at the axial locations compared with off axis locations. The phase averaged axial velocity variation of the droplets is high compared to that of phase averaged radial and tangential velocities with in an acoustic cycle. Periodic clustering of droplets in the spray field is observed in the presence of acoustic field. A maximum particle count of 14 times the minimum count in a phase angle bin is observed within an acoustic cycle for the acoustic pressure amplitude of 3000 Pa. The droplet diameter distribution in the spray field is affected in the presence of acoustic oscillations.
