Abstract

An investigation was conducted to analyse the pattern of entrained air around a high pressure flat spray water jet with emphasis on the determining inter-depency on droplet velocities, droplet size, and the air velocities around a flat jet atomiser. Applications of spray and its surrounding air interaction based on the aerodynamic properties have been very common in the area of combustion, spray painting, spray dryer, fewer research have been conducted on high pressure surroundings especially for flat water jets, until recently in the cleaning oil and gas production systems using high pressure water jets. While other research concentrates on using fuel such as diesel and iso-octane, this research utilised the water flat spray jet. The air flow pattern around a fan jet spray in both downstream and radial components of the entrained-air velocities and its effect on the atomization process as the droplets moves from the nozzle exit using both Phase Doppler Anemometry (PDA) and Hot Wire Anemometry (HWA). Findings from this research provide an envelope of the spray characteristics at range of high pressure up to 10.0MPa, at various downstream and radial positions through the flat spray, which identify the rate of air entrained in the region of primary and secondary atomization.
