摘要:
以数据中心机房某一孔板及其相邻机柜为研究对象,采用ANSYS有限元分析方法,对孔板和机柜建立3种不同的有限元模型:几何实体模型、缩小送风孔板风口面积的基础模型、将孔板视为多孔介质面并添加源项的优化模型。根据实测数据确定3种模型的边界条件,通过有限元仿真计算获得它们的压力、速度云图,将基础模型和优化模型分别与几何实体模型进行对比。结果表明,优化模型与几何实体模型的速度场和压力场的大小误差在5%以内,同时优化模型的计算时间相较于几何实体模型可以减少60%。
Abstract:
Taking the air flow of a perforated plate and its adjacent racks in a data center room as an example, we constructed three finite element models which are real model, basic model and optimal model by ANSYS. The boundary conditions were determined according to the measured data. The contour plots of pressure and velocity of three models were obtained. The basic model and optimal model were compared with the real model. The results show that the deviation of the velocity and pressure between the optimal model and the real model is within 5%. In the meantime, the calculation time of the optimal model can be reduced by 60% compared with the real model.
