RADIATION MODELING ON METHANOL WHIRLING FLAME
This paper numerically investigates the effects of the internal fire whirls induced through air entrainment in an enclosed configuration. Fire whirl is a non-premixed swirling flame originated by unbalanced air entrainment. The fluid motion of the fire whirl is assumed to be a low-speed turbulent reacting flow. The Large-Eddy Simulation with single-step combustion model and Discrete Ordinate Method used to determine the dynamically transient behavior of a methanol whirling flame formulated under air entrainment conditions in an enclosed configuration of dimensions 0.35 m × 0.35 m × 1.45 m. An open-source solver, fireFoam, was used to carry out the computational work. The flame temperature profiles were compared with the published experimental and numerical data. The methanol whirling flame produces hot gases such as CO2 and H2O; the main participating gases for the radiative heat transfer.
