Abstract

Spray characteristics of three liquids, water. diesel fuel,  and kerosene. sprayed  vertically downward in a transparent squared section rube which is accessed with an  exhauster through  Doppler Particle  a pressure swirl atomizer, have been evaluated by means of Phase  Analyzer (PIDPA) system. The experimental apparatus is accessed  with a traversing system which enables to make complete scan. radially and axially, for  the spray cone. Different pressure differentials across the nozzle are applied to study  their effect on spray characteristics. Measurements of drop let mean diameter, droplet size  distribution . droplet mean velocity, liquid volume flux and droplet number density have  been carried out.  Experimental results showed that the droplet size increases and droplet axial mean  velocity decreases as the radial distance from spray axis increases. Also, as the axial distance from the nozzle plane increases. the droplet axial   mean velocity decreases for  the used liquids. the droplet mean diameter and liquid volume flux decrease for both  water and diesel fuel but deviation is observed for kerosene. and the droplet number  density increases for all used liquids. As the pressure differential across the nozzle  increases, both droplet mean diameter and liquid volume flux decreases. and the axial  mean velocity increases. for the used liquids. Data analysis shows that the mass median  diameter to Sauter mean diameter ratio is affected by the pressure differential across  the nozzle, and by Rosin-Rammler exponent, which is a measure of the width of  distribution . kerosene, always. has the smallest drop let mean diameter, and water, in  most of cases. has the largest mean diameter. Sometimes, diesel fuel competes water  having the largest mean diameter.
