“…The gas-phase fuel volatiles emission is controlled by the liquid fuel evaporation. The value of heat generation through combustion is specified by summation of the species mass fraction, which multiplies its formation heat [54].…”

“…This term is therefore assumed to be zero on the boundary. It should be said that the liquid fuel modeling in some computational codes such as the Fire Dynamics Simulator [54] does not have moving interface properties. The depth of the pool fire therefore cannot be directly simulated and must be accounted for using other methods.…”

Fire whirls are a particular case of flame behaviour characterized by a rotating column of fire driven by intense convective heating of air close to the ground. They typically result in a substantial increase in burning rate, temperature, and flame height. Fire whirls can occur in any intense flame environment, including urban areas, particularly within combustible structures, and in wildland or forest fires. Recently, investigations on the creation of fire whirls have attracted much attention. However, most analyses are focused on fire whirl structure, formation, and controlling their unique state. In effect, revisiting the available experimental techniques and numerical simulations used in analyzing fire whirls has received less attention. In this paper, experimental arrangements including empirical set ups and employed fuels are presented in detail. Subsequently, major research progress focused on experimental studies and their laboratory setup is fully discussed, followed by the available numerical simulations, including combustion and turbulence models. Applied methodologies and chosen software in the recent numerical studies are also reviewed exclusively. Finally, the latest findings are featured, and prospective pathways are advised.
