Turbulent closure and the modelling of fire by using computational fluid dynamics

The consequences of fluctuation and intermittency in the velocity and scalar properties of fires are examined from the perspective of their modelling by using computational fluid dynamics. The effects of interactions of turbulence with reaction kinetics, soot formation and radiant heat transfer are discussed, and illustrations are provided of the application of various closures, simple and complex, to the problems of smoke movement and solid–phase combustion.
