Throughout a fully included compartment fire or when a compartment fire is air flow-managed, much more comprehensive combustion is accomplished at People locations in which the combination is suitable. Several reports relating to air flow-managed fires throughout the many years have launched a concept of a ventilation element (( A _vsqrt h_v )) and illustrated the value of ventilation openings on the fire’s expansion by examining the dimensions of air flow openings, destinations of these openings within the compartment as well as the shear mixing that occurs with the interface with the opening (Kawagoe 1958; Thomas and Heslden 1972; Harmathy 1972; Thomas and Bennets 1999; Utiskul 2007; Sugawa et al.
