downflow
Flow moving down
Downflow is movement or flow in a downward direction.
The term appears in technical contexts describing liquids, gases, or air moving from higher to lower positions: The downflow of cold air from the vent.
In HVAC systems, a downflow furnace pushes heated air downward through ductwork.
The word contrasts with upflow.
