摘要:
以数据机房某一孔板上方的冷通道及其相邻机柜中的服务器作为研究对象,采用计算流体力学分析(FLUENT)方法,对冷通道和服务器建立3种不同的CFD模型:几何实体模型,出口面采用多孔阶跃的原始模型,将服务器整体视为多孔区域的优化模型。采用实验测量数据作为3种模型的边界条件,通过仿真计算获得它们的速度场及温度场并与实验测量数据比较,且分别沿着服务器的高度方向(Z轴)和深度方向(X轴)对3种模型中服务器内部的温度进行比较。结果表明:优化模型与实验测量数据的速度场和温度场最大误差分别为3.7%和0.6%,且优化模型与实体模型的温度场的最大误差为0.3%,同时优化模型的计算时间相较于实体模型可以减少58%。
Abstract:
Taking the air flow of the cold aisle and its adjacent servers in a data center as a study case, we constructed three computation fluid dynamics models including real geometrical model, original model and optimal model by FLUENT. The boundary conditions were determined according to the experimental measurement data. The velocity and temperature fields obtained from both computational fluid dynamics model and experimental measurement data were compared. In addition, the air temperature distribution from these models was compared along the height direction (Z axis) and depth direction (X axis) of the server. The results show that the maximum deviation of velocity and temperature fields between the simulated data of the optimal model and the experimental measurement data is 3.7% and 0.6%, respectively. The maximum deviation of the temperature between the optimal model and the real geometric model is 0.3%. Moreover, the calculation time of the optimal model can be reduced by 58% compared with that of the real geometrical model.
