Dunn-Rankin studies combustion, sprays and particles using optical diagnostics and laser spectroscopy.
Generally, he is interested in the fundamental information that can be obtained from simplified systems, such as linear droplet arrays, two-dimensional gas burners, and sub-scale ventilation and biomedical environments, which mimic a specific behavior in more complex systems. Using non-intrusive laser diagnostics, he probes the simplified systems in order to develop physical insight into influencing factors.
His current research activities include a study of the electrical aspects of microgravity combustion; an effort to develop techniques to measure the size of airborne droplets and particles using laser light scattering; and development of a hydrogen-enhanced IC engine. Dunn-Rankin also is studying combustion control, the formation of droplet streams at high ambient density, and acoustic interactions with burning droplets.
His work can be applied in the area of combustion for size reduction, performance improvement, and emissions reduction in the area of spray processing for the novel production of biomedically relevant materials.
