WebThis phenomenon is thought to result from a coupling effect based on heat feedback from the opposite flame and air entrainment due to the chimney effect. Both are modified by changing the adjacent angle, as discussed below. Table 2. Fuel combustion percentages at various adjacent façade angles. The stack effect or chimney effect is the movement of air into and out of buildings through unsealed openings, chimneys, flue-gas stacks, or other containers, resulting from air buoyancy. Buoyancy occurs due to a difference in indoor-to-outdoor air density resulting from temperature and moisture … See more Since buildings are not totally sealed (at the very minimum, there is always a ground level entrance), the stack effect will cause air infiltration. During the heating season, the warmer indoor air rises up through the building … See more There is a pressure difference between the outside air and the air inside the building caused by the difference in temperature between the outside air and the inside air.

WebThe stack effect is sometimes called the Chimney effect This is an air current or movement caused by the displacement of air due to its buoyancy. This buoyancy is primarily caused by heat. Typically “hot air rises cold air sinks”. Occasionally this can be caused by altering the chemical makeup of the gasses in the air. http://www.vsrda.org/how-scent-and-airflow-works
