This modular infrastructure lets you characterise the flow-acoustic (sound transmission, reflection and absorption under various flow conditions, aerodynamic sound generation,...) of duct components from e.g. HVAC, intake or exhaust systems.


Location: FlandersMake@.KULeuven

Technical specifications

Technical specifications of the flow-acoustic characterisation of duct systems:

  • Modular system with circular or rectangular ducts of various dimension
  • Max flow rate: 650 m³/h
  • Flow conditioning: uniform  (frequency regulated roots blower) or time-pulsating (cold engine simulator) at ambient temperature


What do we offer?

  • Flow-acoustic characterisation of duct components: sound transmission and reflection; aerodynamic noise generation.
  • Characterisation of sound absorbing materials (micro-perforates, liners, porous wall treatments, …) under grazing flow.
