Announcements Are you looking for a fast, accurate and complete solution for determining Ducts and Exhausts/Mufflers noise performance and emissions sound quality?

Join NUMECA for this FREE webinar on FINE™/Acoustics, NUMECA’s integrated environment for the Aero-Vibro-Acoustic simulation, on September 30th, 2015!


Sponsor CFD Review

Since recent regulations and market trends require limited exhaust noise emissions and enhanced sound quality, designers and manufacturers need to produce optimized designs. Reaching this objective means relying on tools and methodologies offering complete, accurate, fast and cost-effective solutions. These regulations concern cars, motorbikes, vehicles in general, HVAC systems, power generation systems, vacuum cleaners, etc.

By attending this webinar you will benefit from a demonstration of the capabilities of FINE™/Acoustics and the whole NUMECA CFD Integrated environment for the analysis of Exhaust Systems and Mufflers. i.e.:

  • Automatic generation of acoustic and CFD meshes on complex geometries (HEXPRESS™/Hybrid)
  • Integrated Aero-Vibro-Acoustic simulation (FINE™/Acoustics):
    • Air-borne noise propagated through the duct (Pipe-Noise)
    • Sound absorption produced by mufflers (Transmission Loss)
    • Structure-borne noise generated by structural vibration (Shell-Noise)
    • Flow-Noise due to the turbulence generated in confined flows (ducts, mufflers) and in exhausted flows (tail pipes)
  • CFD simulation of a muffler’s back-pressure and of the internal/exhausted flow (FINE™/Open with OpenLabs™).
