ABSTRACT

The combustion characteristics of single (fuel or oxidizer) droplets, are of great significance in the development of devices which use spray combustion. The lack of essential information about some of the basic mechanisms governing the liquid burning at sub- and particularly at super-critical pressures has led to recent experimental investigations utilizing image analysis in an attempt to answer some of the questions. This paper presents a computerized video image processing system which has been developed and built in order to study the behavior of evaporating/burning liquid droplets at atmospheric conditions as well as at high pressures. The system is based on computerized processing and analysis of video images, using a CCD camera, 486 PC computer and image analysis software. Comparison of variations in droplet size and shape in consecutive pictures can be done automatically, thereby deriving the burning rate and detecting other phenomena. A detailed description of the apparatus components is given along with elaboration of the system capabilities and limitations. Representative images and analysis of burning droplets at various pressures are also presented.
