Dataset to "Comparison of scattering phase functions of reacting and non-reacting pulverised fuel particles"

This study investigates the scattering properties of cold and reacting (burning) particles, focusing on the experimental quantification of the complex index of refraction (IOR) for wavelengths between 400 nm and 950 nm. The scattering phase function for Colombian bituminous coal is measured experimentally using two different setups, and the IOR is determined from these data using an inverse approach. The first experimental setup (called Setup A) is designed for single cold fuel particle characterization, with the particle being spatially fixed contactless using an acoustic levitator. In the second setup (called Setup B), the scattering properties of particle streaks, provided by a flat flame burner, are measured, also allowing for reacting particles to be investigated. In both setups, a broadband light source irradiates the single particle/particle streak, and the scattered radiation is quantified by a spectrometer placed at altering angular positions. Reacting particles are studied in an oxy-fuel atmosphere. Mie theory is used for both setups to model the optical particle properties.The Dataset contains the measured phase functions and the calculated IORs.
