Air flow-generated fire patterns are described inside the literature as having a slight influence all through fuel-controlled ailments, but become the predominant challenge with the location and magnitude of damage following the compartment fire is ventilation-controlled (Shanley et al. 1997; NFPA 2014; Carman 2008). To start with, throughout gas-controlled problems air flow has become shown to induce the fire plume to lean faraway from the supply of air flow due to momentum flows in the inflow, thus influencing the truncated cone form (Shanley et al.

The combustion of the fuel by way of diffusion flames is inherently oxygen limited with the diffusion response and the availability of only 21 % of oxygen in air in properly-ventilated fires.
