CFD Modelling

Case Study

This Global financial organisation, with headquarters based in London, provides financing and risk management services to a number of large companies, institutions and government clients.

With offices in almost 30 countries around the world and employing over 20,000 people, ensuring that all data centre are operating to their full potential is a key operational strategy.

The Brief

The Client invited us two existing, state-of-the-art data halls, each with a floor area of over 1,500m2 and containing over 300 racks.

Sudlows were engaged to explore the possibility of increasing the amount of IT equipment that could be contained within each data hall, without additional mechanical plant.

The critical nature of the data centres necessitated a non-invasive approach that guaranteed zero downtime and minimised operational risk.

Computational Fluid Dynamics (CFD) technology was used to assess the cooling airflow available to each new and existing rack, providing the client with key information about the maximum airflow consumption each rack could potentially support.

The Conclusion

By utilising CFD analysis, the Sudlows data centre audit team essentially ‘found’ an extra 90kW of capacity which enabled the client to install an additional 94 cabinets without having to install any costly supporting plant.

The final assessment also proposed a method of energy saving through governing the CRAH units.

The effect each of the CRAH units had on the new aisles was found, allowing the new regions to be effectively controlled by the existing control system.

This CFD analysis ensured that the new cabinets could be installed without risk to the existing data hall and with maximum capacities provided to the IT team to ensure that the data centre could be adequately cooled as it was populated.
