基于CFD模拟的数据中心集中式模型研究

Centralized Data Center Model based on CFD Simulation

对以往的分布式模型(CFD模拟)和集中式模型两种计算方法进行了介绍,然后对机房模型进行了简化并选取典型工况进行CFD模拟,得到该工况下的气流组织及温度分布情况,总结几种工况温度分布规律,建立集中式数学模型,并进行了验证。总结出了一种新型集中式数学模型的建模思路。

To reduce energy consumption of a data centre,a real-time and dynamic monitoring is needed.There are mainly two methods to calculate temperature distribution in datacenter,distributed model（CFD simulation） and centralized model.Distributed model can only calculate under a definite condition,and traditional centralized model calculations have a big tolerance.Firstly,we introduce both of the methods,then simplify the datacenter model and simulate under a typical condition,at last give out the centralized model from the simulation results.This method is a combination of distributed and centralized calculations,which is more rapid and accurate.
