街道峡谷中机动车排放污染物的扩散取决于屋顶风向和风速,并受街道峡谷宽高比、峡谷两侧街区建筑物高度的对称性和高度分布及街区形状等因素的影响.街道峡谷宽高比接近1时,递升型峡谷以及宽阔街道有利于污染物的扩散;可以通过改变街道线源附近街区内建筑物的高度来明显降低污染物浓度.城市建筑规划中若科学考虑上述影响可以减少街道峡谷内污染物的积聚.联合国发展计划署(UNDP)资助项目中文核心期刊要目总览(PKU)中国科学引文数据库(CSCD)0151-541

应用雷诺应力湍流模型,模拟了不同高度比的城市街道峡谷的气流场.结果表明:峡谷的对称性对其内部气流场有显著影响.前高后低型峡谷下部为逆时针旋涡,上部为顺时针旋涡,峡谷越深,流场发展的越充分;峡谷内部墙面...
机动车尾气排放不断增加以及城市通风能力降低,常导致城市街谷内的空气污染.城市街谷大气环境主要研究方法包括外场观测、实验室物理模拟和数值计算.外场观测和物理模拟可以考察街谷内污染物的传输扩散规律并对数值...
