CFD, or Computational Fluid Dynamics, is a modelling process that illustrates the flow of liquids and gasses through and around 3D and solid surfaces. In the data center world, it is utilized to make decisions regarding airflow, containment and cooling as well as layout, power consumption and more.

 

A number of software applications are available to develop these predictive models; the key factors in the software efficiency are computational capacity and speed. Using those tools, technicians first measure the energy, density, inertia, temperature, viscosity and other attributes of a particular element in the room or in the entire data center. However, the smaller the area, the more accurate the study results will be.

 

Comparative measurements are gathered and digested by the software with the end result as a detailed thermal image or set of images, providing a comprehensive picture of present data center conditions.

Why Use CFD Analysis in the Data Center?

 

CFD analysis can illustrate a number of scenarios that are integral for data center decision making, including:

 

·         Hardware selection

o    Which component cools better through a server?

 

·         CRAC/CRAH unit placement

o    Are these units placed optimally throughout the space? Are additional units required? Should some be removed?

 

·         Hot/cold aisle monitoring

o    Are the cold and/or hot aisles within the suggested temperature range for the equipment therein?

 

·         Floor tiles and fans

o    Are ventilated floor tile and fan placement accurate? How much are they improving energy efficiency?

 

·         Hot spots

o    Where are they? How can they be remedied? Is any of my equipment in immediate danger?

 

·         Blanking panels

o    In which locations would these be useful?

 

·         Air leakage

o    How much? How often? How secure are the ceiling plenum and underfloor plenum?

 

CFD analysis in the data center, combined with power monitoring and DCIM, can be a useful tool to reduce data center risk and protect data center assets as well as reduce operational costs and optimize energy consumption. To speak with a CFD specialist, contact us today.
