介绍了一种利用计算流体动力学技术分析通信机房流场分布的方法,找出合理的气流组织形式以达到节能的目的。对机房三维物理模型进行非结构化网格划分,选用标准的k-ε湍流模型,设定相应的边界条件,针对不同的空调风速工况,利用Fluent软件对机房内的温度场和速度场进行数值模拟与分析,研究得出合理的风速以降低能耗。该方法能够有效地建立通信机房的流场模型,对制定机房节能方案有重要的参考作用。

A way to analyze the distribution of flow field in communication equipment room by using computa- tional fluid dynamics （CFD） is presented to find the reasonable air distribution form and save energy. The three-dimensional physical model of communication equipment room is partitioned into unstructured mesh, the standard k-ε turbulence model is selected, and the corresponding boundary conditions are set. Under different wind speed conditions, the temperature field and velocity field in the room are simulated and analyzed by Flu- ent software, and the reasonable air speed is obtained to reduce energy consumption. This way can effectively establish the flow field model of communication equipment room, which has an important reference function for developing energy-saving programs.
