The University of Texas at Dallas has conducted research on potential new organic exciplex systems for use in fluorescent visualization of the vapor and liquid portions of evaporating fuel sprays. These exciplex systems represent a novel and potentially powerful diagnostic tool for the analysis of the vaporization processes in gas turbine fuel sprays, and as such possess considerable relevance to Air Force propulsion needs. This final report describes the five best exciplex systems developed to date, the methods used to screen nearly one hundred of potential systems, and the characterization of the naphthalenetetramethyl-p-phenylene diamine system. This last system has already been used in demonstration experiments to photograph the separate liquid and vapor patterns in an evaporating fuel spray.
