Yet another problem would be that the styles talked over are assuming an idealized fire plume which is formed to be a cone, that is a gross oversimplification. Shanley et al. (1997)) explained the phenomenon that air flow to the space was capable to alter the truncated cone condition expected from your flame and fire plume by “leaning or pushing of 1 facet of your pattern far from the source of ventilation” (Shanley et al.
The authors advised that the investigator could Assess the products involved and “the variations of flammability of combustibles along the route of journey might demonstrate the route of journey or distribute” (Straeter and Crawford 1955). Additionally they discussed that spots and situations of air flow openings as working in “two different capacities, where by the fire could go to the subsequent space…or it might be a supply of incoming air to feed the fire” (Straeter and Crawford 1955).
