藏东南地区民房建筑特点及其室内流场模拟研究

Research on Architectural Characteristics and Indoor Flow Field Simulation of Residential Buildings in Southeast Tibet

藏东南沿尼洋河——雅鲁藏布江河谷地带房屋建筑丰富多样,伴随习俗、地域地形和环境不一样存在各式各样的房屋建筑结构。在调查统计的基础上,建立了独立型窗户透光辐射模型和基于空调供暖的自然对流模型,并采用计算流体动力学方法对房屋室内流场情况进行了模拟,掌握了室内空气流动状态和墙面结构温度分布情况,为后续建筑供暖节能提供了有利的支撑。

Tibet southeast along the Niyang River--Yarlung Zangbo River valley. There housing construction is rich and varied, with customs, different terrain and environment exist all kinds of building structure. On the basis of the investigation statistics, the independent model window light radiation model and the warm air conditioning natural convection model were established, and the computational fluid dynamics method is adopted to study the indoor flow field simulation, mastered the indoor air flow state and the wall temperature distribution of structure, provided a favorable support for the subsequent building heating energy saving.
