Computational fluid dynamics is the use of applied mathematics, physics and computational software to visualize how a gas or liquid flows and learn how it affects objects as it flows past.
In information technology (IT), CFD software can be used to create a 3D mathematical model that represents a data center. By changing variables, an administrator can quickly visualize how cold air will flow through the data center under a given set of circumstances. CFD is useful for identifying hot spots and areas of the data center that are wasting cold air.
Identifying the hot spots allows the administrator to apply targeted cooling rather than using a scattershot approach to try and keep the average temperature of the data center within certain limits. Many organizations are surprised by how much they can save just by targeting the cooling and removing any focus from those components that run well within a recommended thermal envelope without any cooling.
CFD is also useful for optimizing capacity and predicting how hardware changes will affect the environment. For example, it may be beyond the capabilities of the existing system to effectively cool a certain rack full of spinning disks. However, by splitting the disks across two racks and placing low-energy network equipment in the space cleared could enable the existing cooling process to deal with the heat load and would also avoid incurring additional expense.
