CFD Lab – Virtual Testing
Reliable virtual testing of airflow products: fast, visual, and cost-effective.

​​​​

Deratec’s CFD Lab provides fast and accurate simulations to assess airflow, pressure drop, rain rejection, acoustic and more — without the need for physical testing.

Our results have been verified against physical test data, giving you confidence in performance outcomes while saving time and cost.

 

What We Test:

• Airflow rate and velocity distribution

• Pressure drop through components

• ADPI, Throw and coverage (e.g. for diffusers)

• Rain resistance and water proof

• Wind loading (for exposed components)

• Sound transmission loss/insertion loss

​

Applications:

• Louvres (rain, pressure drop, wind loading, acoustic)

• Roof ventilators (rain, pressure drop, acoustic)

• Fans & filters (pressure drop, backpressure)

• Diffusers & grilles (throw pattern, ADPI)

• Other custom ventilation parts

​

Standards Referenced:

We simulate according to key principles from:

• AS/NZS 4740 (louvres and ventilators)

• AS1191 & ISO 717-1(louvres and ventilators)

• ASHRAE guidelines (diffusers and grilles)

• ISO 5801 (fans)

• Other applicable test standards based on product type and application​
