2008). This brings about the plume to widen horizontally during the higher layer creating damage to the intersecting surfaces. A two-dimensional fire pattern is anticipated to sort over the vertical surface interface (i.e. walls) in the form of a funnel or cone Using the vertex at the bottom. This fire pattern has become proposed to indicate a gas deal which has achieved a HRR enough to make a flame plume that here reaches the horizontal floor (i.e. ceiling).
