When discharging the cool air from the slot (VAV outlet), the air pattern remains horizontal on the ceiling until the separation occurs. After the separation, the cool air drops down into the occupied zone. From the view point of the air distribution, it is important to predict the separation point. According to the boundary layer theory of fluid dynamics, it seems impossible that the separation of the cool air occurs on the ceiling, because the air accelerated by the difference of the static pressure along the flow direction. The cool air, however, actually drops down. The author carried out a series of experiments with replacing the cool air by the warm air with the same buoyancy. After the experiments, the author is of the opinion that it occurs at the point where the total pressure of the air flow becomes equal to environmental stagnant air pressure. The experimental results and the theoretical analysis are presented in this paper.
