摘要:

针对受多种因素影响的单体房间风压通风问题,通过一系列风洞试验并结合数值模拟手段,分析改变窗墙比、前后建筑表面风压差、进出风口面积比和前后开孔相对位置这4个因素对室内通风量的影响.获得了描述通风量与窗墙比、风压差之间关系的经验公式,引入新参数使其能够反映进出风口面积比和前后开孔相对位置改变的影响.研究结果表明:通风量与窗墙比成正比关系;通风量随着建筑物前后表面风压差的增大而增大;当总窗墙比不变时,前后开孔面积越接近,通风效果越好.

关键词: 通风窗墙比风压差数值模拟风洞试验    
Abstract:

For single room, wind-driven ventilation is affected by miscellaneous factors simultaneously. The impact of wall porosity, the pressure difference between windward and leeward, area ratio of inlet to outlet and the relative position of windows on windward and leeward was analyzed through a series of wind tunnel experiments in association with numerical simulation. Then the empirical formula that described the relationship among the flow rate, wall porosity, and wind pressure difference was achieved. New parameter was involved in the formula to consider influence of inlet and outlet area ratio and the relative position of indoors on windward and leeward. Results show that flow rate rises proportionally to windward wall porosity and it becomes larger with the increase of wind pressure difference. If the total wall porosity is constant, the smaller the difference between the inlet and outlet area is the better ventilation can be attained.

Key words: ventilation    wall porosity    wind pressure difference    numerical simulation    wind tunnel experiment
