Information

This model illustrates buoyancy-driven natural ventilation between two volumes of air. The volume volA can be considered as the volume of a room, and the volume volOut is parameterized to be very large to emulate outside air. The outside air is 20°C and at initial time, the room air is 18°C. This induces an airflow in counter clock-wise direction. Since heat is added to the room air volume, its temperature raises above the temperature of the outside, which causes the air flow to reverse its direction.
