Abstract

Spray characterization remains as an important component of research and development for advanced energy conversion systems. In these environments, the sprays are generally associated with complexities such as turbulent flows, drop collisions, secondary break-up, evaporation, material changes in the droplets, evaporation and condensation, combustion-generated particulate, and thermally-induced refractive index fluctuations. Thus, the difficulties confronting combustion researchers, and the challenges for the spray characterization methods, should not be underestimated. Complete characterizations of spray systems are difficult and seldom reported in sufficient detail. Experiments designed to characterize the complete spray combustion process require a number of different diagnostics and measurement tasks involving both commercially available diagnostics and some unique diagnostic capabilities that are not yet commercially available. Depending on the level of research and development conducted, information on the internal flow of the atomization system, liquid discharge characteristics, sheet thickness, velocity, cone angle, and sheet break-up mechanisms may be of interest.
