Abstract
Exciplex-based liquid/vapor visualization systems used for fuel distribution studies allow 2D fluorescent images of the two phases to be taken separately. Although the exciplex technique is not new, an improved quantitative calibration method has been developed, relating fluorescence intensity to mass concentration of liquid and vapor fuel. Multiple droplet summation of optically thin droplets should be used to generate liquid phase calibrations for use in studies with high-pressure injectors. In addition to eliminating the need to correct for optical density, the spatial-averaging effect of this method resulted in a repeatable calibration.
