Description:
Air and fuel transport systems usually comprise many closed branches, which are known to give rise to aero-acoustical instabilities. Steady pulsation amplitudes are reached as a result of non-linear saturation.
A study of the aeroacoustics of complex pipe systems has been initiated considering as a prototype a row of closed side branches placed along a main pipe [1,2,4,5,6,7]. For shallow closed side branches a behavior similar to that of so-called corrugated pipes has been observed. We are currently considering the case of multiple deep closed branches [3]. The main goal of our research is the development of simplified non-linear models describing the coupling of vortex shedding with acoustical resonance. This work is sponsored by the European Commission Marie Curie RTN Project AETHER (http://aether.cerfacs.fr/), Contract no. MRTN-CT-2006- 035713.
