Convective heat transfer around vertical jet fires: An experimental study

► Experiments were carried out to analyze convection around a vertical jet fire. ► Convection heat transfer is enhanced increasing the flame length. ► Nusselt number grows with higher values of Rayleigh and Reynolds numbers. ► In subsonic flames, Nusselt number increases with Froude number. ► Convection and radiation are equally important in causing a domino effect.
