Abstract
One of the significant problems in the present design method of natural ventilation is that the influence of turbulent wind on ventilation is taken no account of. The purpose of this study is to investigate the effect of the turbulent wind on ventilation rate of a room and finally to establish the design method of natural ventilation in which this effect is taken into account. In this paper, to examine the additional ventilation rate caused by turbulent wind, experiments to ventilate an enclosure with two openings, one of which faces to windward of artifitial wind and the other lies leeward, are carried out. Then to make the mechanism of ventilation caused by turbulence clear, the air flow through a windward opening is visualized by tabacco smoke. Consequently it turned out that the turbulence of wind causes the additional ventilation rate if the windward opening is over two times as large as the leeward opening and that in such cases the inflow and outflow through a windward opening occur at the same time.
