Radial analysis of fine sprays using Phase Doppler Anemometry (PDA)

Abstract

A mobile fine spray unit, utilising a Spill Return Atomiser (SRA) has been developed for the purpose of decontamination within healthcare environments. The unit must be able to spray uniformly onto any given surface,
providing ‘mist like’ coverage. Any uneven coating would jeopardise the efficiency of delivering the decontaminant fluid. Thus it is pertinent to understand and analyse the characteristics of the spray at various radial and
downstream locations within the full cone patternation produced by the SRA.
PDA equipment was used to acquire Sauter Mean Diameter (SMD), droplet velocity and mass flux data at set radial positions across the spray and at various distances downstream of the atomiser. The results provided a comprehensive analysis of the spray and were used to determine the most effective coating distance to achieve ‘mist
like’ coverage for delivering a decontaminant fluid.
