Aerodynamic measurements: Boundary layer components

 

Understanding laminar flow, turbulent flow and the transition region

As examined in the What is the difference between acoustic and aeroacoustics? article, the studies of aerodynamics and aeroacoustics are bound together. Using microphones, surface- or flush-mounted, in a wind tunnel focuses on measuring the characteristics of air pressure in the boundary layer of an object in flow through a medium (or the medium around the object).

Aerodynamics, Aeroacoustics, Turbulence and Boundary Layers, Oh My…

 

Where does your noise come from?

Our perception of what is and is not an acceptable noise level has changed a great deal in the past 100, or even 25 years. The change in designs for improvements in transit times, fuel economy and even energy production are visible all around us and impact our daily lives. Vehicles on the motorway, local commuter and high-speed trains, aircraft, and wind turbines all impact our lives in various ways, including the addition of noise.

What is the difference between acoustics and aeroacoustics?

 

The answer is…

Aeroacoustics is a subset of the field of acoustics. The end...

But before you go, it’s not quite so simple as it may seem, and it is much more interesting.
