Modelling and simulation of aeroacoustic phenomena has progressed massively since the introduction of Lighthill’s analogy. New simulation methods and larger access to computational power allow large corporations in the automotive and aerospace sector to tackle problems such aircraft exhaust noise, side mirror noise, HVAC (Heating, Ventilation, and Air Conditioning) noise. On one side, the aeroacoustic community is very active on improving the accuracy and maturity level on these applications; on the other side, the community looks as well to new technologies which would be better suited to tackle markets which have a larger variety of products and combination of system which are not affordable at reasonable cost with combined unsteady flow and acoustic simulations. A representative important market for the last category is electronics where the combination of components and cooling fans are almost infinite. Challenges such as better fan noise prediction, complete system simulation including structures and acoustic treatments and high frequency accuracy will require new methods and workflows to be part of the design process of engineering companies. This paper will perform an overview of the aeroacoustic modeling techniques and methods, discuss the challenges that companies are facing when using aeroacoustic simulation, address the gaps in processes for making aeroacoustic simulation more accessible and examine the trends for the decades to come.
