摘要:
曲面型建筑在我国及世界上源远流长,这些曲面造型融合了建筑师的灵感与其环境、功能、结构等因素.曲面形状以多种形体构成,本文以最速降线曲面为例,探究基于曲面贴附送风模式气流组织形式的适用性.通过CFD数值模拟和理论分析相结合的方式,研究了最速降线曲面贴附送风形式在不同曲率、送风速度和温度下室内的速度场和温度场分布.研究表明,贴附送风可以适用于最速降线曲面,且是一种通风效率较高、工作区人员热舒适性较好的气流组织形式,可以推广到圆形、椭圆形和抛物线形等多种形状
Abstract:
The curved building in our country and the world has a long history, and these curved surfaces blend the architect ’s inspiration with its environment, function, and structure, and other factors. The shape of the curved surface is made up of various shapes in this paper,and the brachistochrone curved wall was used as an example to explore the applicability of the air distribution of attached air curtain ventilation. By combining CFD numerical simulation and theoretical analysis method, the velocity field and temperature field distribution in the room with different surface curvature, air supply velocity and temperature were studied. Results show that the attached air curtain ventilation mode can be applied to brachistochrone curved wall, and it can create a comfortable environment in the occupied zone with high ventilation efficiency. Therefore, the attached air curtain ventilation mode can be applied to the space of the building with circular, elliptical, parabola and other building planar shape.
