Effervescent sprays are shaped by internal two-phase flow, gas--liquid momentum exchange, and interaction with the surrounding environment. This study introduces an infodynamic framework to characterize droplet size diversity using informature, differential informature, the Activation Factor, and the Representation Index (). Differential informature provides a measurement-alphabet-independent description of spray informational structure, while () identifies whether number, interfacial area, or liquid volume is carried by coherent or scale-separated droplet populations. Applied to PDI measurements at different gas-to-liquid ratios, the method revealed an info-hollow-cone structure and distinct radial information-carrier regions linked to effervescent spray development.
