基于PHOENICS的办公楼通风效果的数值研究

摘要

Commercial software is applied to simulate the numerical ventilation effect of certain office building. Based on the Reynolds time-averaged equation method and the RNGk-εturbulence model, with simulation results of the outdoor environment as boundary conditions, the calculation is to find out the flow distribution, wind speed and ventilation of the main functional space of this building. Research shows that it is possible to estimate the overall ventilation effect of the architectures by using numerical methods, which is of great significance for the design of functional spaces where strict ventilation is required.%应用商业软件对某办公楼的通风效果做了数值模拟。计算基于Reynolds的时均控制方程以及RNG k-ε湍流模型并以建筑室外环境模拟结果作为边界条件，求解办公楼主要功能空间的流场、风速以及通风量。研究表明，使用数值方法可对建筑空间整体通风效果进行估算，对于有严格要求的功能空间的通风设计具有一定的参考意义。
