In a corner setting, a fire in fuel packages can only entrain air from which of the following?

In a corner setting, a fire in fuel packages can entrain air from two sides. This occurs because, in a corner, the fire has the potential to draw air into the combustion zone from the two adjacent walls that are closest to the flame.

The nature of fire behavior in a corner scenario means that while there are obstructions preventing air intake from all sides, the two sides that are open allow for more effective air movement toward the fire. The entrainment of air is crucial for the combustion process, as adequate airflow is necessary to sustain and amplify the fire, making the dynamics of airflow in corners particularly important in fire behavior studies.

In contrast, a fire in an open space would be able to entrain air from all sides, while in a situation where the fire is confined more tightly (such as completely surrounded by walls), it would only be able to draw from the limited openings available. Therefore, understanding the air supply dynamics significantly impacts fire development and behavior in these scenarios.
