This study reports the development of a LES-based numerical model dedicated to the simulation of well-ventilated and under-ventilated purely buoyant fire plumes. A new second-order low-Mach number variable-density flow solver was developed and verified in order to describe accurately the strong unsteady processes related to the purely buoyant nature of the flow. State-of-the art subgrid-scale turbulence, combustion and radiation models were specifically developed, including the non-adiabatic SLF (steady laminar flamelet) and FPV (flamelet/progress variable models). The RCFSK was considered as reference radiative property model whereas the performance of simpler models, including non-grey and grey versions of the weighted-sum-of-grey gases w...
