Interaction between the mixing and displacement modes in a naturally ventilated enclosure

The aim of this paper is to study the interactive phenomena in buoancy-induced natural ventilation in a full-scale enclosure , with upper and lower openings on one of the sidewalls. Experiments reveal the interaction between the mixing and the displacement ventilation with the opening of the lower vent to different heights while the upper vent is kept fully open. The experiments are in agreement with a previous theoretical model.
