Abstract
The use of nanoscopic fibres for acoustic absorption can potentially result in thinner liners than for conventional acoustic materials. Modelling acoustic mechanisms at the nanoscale requires molecular simulations as the flow be-haviour at the nanoscale is in the transition regime (based on Knudsen number). Molecular Dynamics (MD) was identified as a suitable method for simulating the physical phenomena for acoustics. This paper presents a review of previous MD simulations of relevance to the physics of acoustic absorption mechanisms at the nanoscale that have included micro- and nano- scale flow properties and acoustic wave propagation. The paper also discusses additional simulations that can be performed to verify that MD models can be used to correctly simulate acoustic absorption at the nanoscale.
