An experimental analysis is here proposed on water-mist sprays operating at high supply pressure. Advanced laser-based diagnostics has been employed to perform measurements. In particular, a Malvern Spraytec device has been used to measure drop-size distribution at various distances from the injector outlet along the spray axis. Moreover, initial velocity has been determined through a PIV analysis. Some evaluations of the spray-cone angle have been proposed as an additional outcome of the analysis. Different nozzles have been employed to produce the water-mist spray and operative pressure has been set at values of interest for fire-protection applications, which constitute the reference field for the present work.

Abstract

In particular, a Malvern Spraytec device has been used to measure drop-size distribution at various distances from the injector outlet along the spray axis. Moreover, initial velocity has been determined through a PIV analysis. Some evaluations of the spray-cone angle have been proposed as an additional outcome of the analysis. Different nozzles have been employed to produce the water-mist spray and operative pressure has been set at values of interest for fire-protection applications, which constitute the reference field for the present work.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
