夏季北方某建筑群温度模拟与分析

Simulation and Analysis of the Temperature of a Building Group in the North in Summer

本文应用计算流体力学的方法,研究北方某建筑群夏季时的温度变化。根据模拟结果得出,该区域地表温度受建筑物、太阳辐射和风速的影响,温度分布不均;单体建筑外墙温度在垂直方向和水平方向具有一定的分布规律,侧面外墙在垂直方向上的温度分布取决于建筑高度,温度随着建筑高度的增高逐渐降低,顶面在水平方向上的温度分布取决于太阳高度角,在北方夏季同一水平面上顶面温度由西北方向到东南方向递减。

this paper uses the method of computing fluid dynamics method to study the temperature variation of a building group in the north in summer.The simulation results show that the ground temperature in this region is affected by the building,solar radiation and wind speed,and the ground temperature distribution is uneven.The external wall temperature of single building has certain distribution pattern in the vertical and horizontal.The increase of building height makes the external temperature decrease in the vertical direction.The top wall temperature depends on the altitude angle of the sun in the horizontal direction.The top wall temperature gradually decreased from northwest to southeast in the horizontal direction in the north in summer.
