FAQ

Common questions about data centre thermal optimisation

What is data centre thermal optimisation? +

Data centre thermal optimisation uses CFD-based thermal mapping to identify hotspots, optimise cooling airflow paths, and reduce PUE. We build a pre-digital twin of your data hall — letting you test rack additions, cooling changes, and capacity scenarios on the model before committing physical changes.

How does CFD reduce PUE in a data centre? +

CFD reveals where cooling air is wasted — recirculation, bypass airflow, over-provisioned CRAH units, leaky cold aisles. By quantifying these losses, we identify which fixes (containment, blanking panels, set-point changes, capacity rebalancing) deliver the largest PUE reduction. Operators typically see 5–15% PUE improvement after CFD-led tuning.

What is a ROM (Reduced-Order Model) for a data centre? +

A ROM is a fast surrogate model trained on CFD data. Once built, it predicts rack-level temperatures across thousands of rack and cooling configurations in seconds — replacing days of CFD reruns. We use ROMs as ongoing pre-digital twins for capacity planning and operational decisions.

Can you size CDUs for liquid-cooled data centres? +

Yes. Coolant Distribution Units in liquid-cooled data centres are plate heat exchangers — our validated NTU-ε / Martin / Kumar correlations apply directly to CDU thermal performance prediction. We also build configurators that automate CDU sizing for repeated specifications.
