Suppression of cup-burner flames using carbon dioxide inBmicrogravity

The extinguishment characteristics of CO2 as a fire-suppressing agent have been studied experimentally and numerically using a methane–air laminar co-flow diffusion flame stabilized on a cup burner. Direct numerical simulations of cup-burner flames under various gravitational forces were performed using a time-dependent, axisymmetric mathematical model with a detailed-chemical-kinetic mechanism for CH4/O2 combustion. Experiments with cup-burner...
