Study of radiative heat transfer and flow physics from medium-scale methanol pool fire simulations

A medium-scale (30 cm diameter) methanol pool fire was simulated using Sandia National Laboratories’ Sierra/Fuego low-Mach number multi-physics turbulent reacting flow code. Large Eddy Simulation (LES) with subgrid kinetic energy closure used as the turbulence model. Combustion modeled a strained laminar flamelet library approach. Radiative heat transfer gray-gas approximation. This paper details analysis done to support validation study for In this analysis, integral quantities were primarily examined. The radiant fraction computed and model calibration parameter. Integrated buoyancy flux calculated compared an engineering correlation. Entrainment rate without mixture threshold filter correlations. Turbulent effect of mesh size on total Flame height intermittency definition two input parameters. sensitivity then conducted determine estimated flame aided in achieving primary objectives by providing expanding scope effort. addition, range physics examined increased, enhancing understanding model's overall performance relationship between phenomena.
