Abstract

A laser sheet digital imaging system was developed to visualize and characterize aviation fuel sprays through the use of a highresolution camera and a pulsed laser Image processing and particle image velocimetry PIV were employed to investigate the spray development process during an individual injection pulse The experimental setup of the visualization system and the results of spray analysis were presented at both macroscopic and microscopic scales Experiments were conducted with low line pressure ie less than 5 bar in still air through short injection pulses The variation in spray velocity distribution was observed by producing spray PIV at several stages of the injection pulse period A longrange microscope was utilized to provide a closeup view of the microdroplets which are 5–100 μm in diameter Velocity vector fields of the small droplets were produced by applying microPIV tracking technique and acquiring a large number of doubleexposure shadowgraph images for several test pointsRami Zakaria PhD MSc BEng is an assistant professor in the Department of Mechanical System Engineering in Hansung University South Korea He received his PhD on experimental fluid mechanics from the University of Warwick UK in 2013 His research interests include fuel atomization fluid visualization particle image velocimetry combustion rotary engines and optical technology
