城市街道峡谷中建筑屋顶形状对城市微气候环境影响

唐洁 [1], 张双喜 [1],
[1] 武汉大学测绘学院

本文以实际生活中常见的4种屋顶形状的建筑为研究对象,使用COMSOL MULTIPHYCIS 5.3a软件构建了一个二维数值模型,模拟了等高上斜屋顶、下斜屋顶、三角形屋顶、平屋顶筑物屋顶形状对街区峡谷高宽比W/H=1的城市街道峡谷流场以及温度分布影响,同时该模型加载了太阳辐射模块,考虑了建筑表面对表面的辐射效应,模拟了不同太阳辐射角下城市街道峡谷的风速以及温度分布.结果表明等高建筑物下,在不同辐射角度下峡谷内温度分布不同,但背风面容易发生热量的累积,而下斜屋顶更有利于城市街道峡谷的扩散,上斜屋顶更加容易导致热量的累积。这可以为城市规划师和设计师提供了一些建议与想法 ...

铁芯电抗器作为电力系统中重要的基础设备之一,具有漏磁小、节省空间等优点,因此在新能源和城市配电系统中得到广泛应用。但其运行中产生的噪声严重污染周边环境,而且电抗器振动过大对其自身正常运行也会构成威胁。本文在磁致伸缩效应和麦克斯韦方程相关理论研究基础上,采用COMSOL Multiphysics®多物理场仿真软件,通过AC/DC模块、声-固模块对三相电抗器铁芯的振动噪声进行研究。首先从多物理场耦合的角度,定义瞬态计算条件,然后在瞬态磁场的基础上加上声场和固体力场来建立三维物理模型,最后通过多物理场的耦合计算,得到电抗器铁芯振动位移和声压场分布 ... Read More
