aeroacoustics

[‚er·ō·ə′küs·tiks]
(acoustics)
The science of aerodynamically generated sounds, encompassing the study of how such sounds are produced, how they propagate through various media (including propagation through ducts carrying fluid flows), how they interact with obstacles or barriers or wave-bearing surfaces, how they radiate away, how they can be managed or controlled, and how they are measured or predicted.

The acoustic propagation component was conducted using an in-house code that implements the FW-H integral method [18] for computational aeroacoustics. The original FW-H formulation utilized generalized functions to recast the continuity and momentum transport equations into the form of an inhomogeneous wave equation.

The selections that make up the main body of the text are devoted to uncertainty quantification as applied to the aeroacoustics of wall-bounded flows, the efficient uncertainty analysis of radiative heating for planetary entry, metastable conditions in cavitating flows, and other related subjects.
Its ground-up rework brings with it an intense focus on connectivity, driver assistance, aeroacoustics and driving dynamics.
Whilst continuing with the familiar family face of the existing Q5, it is actually new from the ground up with a focus on connectivity, driver assistance, aeroacoustics and driving dynamics.
