“…Moreover, comparable values for m and m ev are reported, despite the differences in the boundary conditions characterizing the system from a thermal point of view. As it is possible to note, the majority of data have been collected for D p > 5 m (i.e., larger than D ∞ ), whereas a dearth of studies can be observed for D p < 1 m. Generally speaking, even if large-scale experimental scenarios have already been tested [26] and modelled [27], quite unexpectedly, small-and medium-scale experiments are rare, as recently observed also by Zhang et al (2018) [28]. To this aim, data on the mass evolution over time can be conveniently integrated by qualitative (e.g., images) and quantitative (e.g., thermocouples and pyrometers) analyses on the thermal aspects in the proximity of a pool fire [29].…”
