“…As a consequence, it can't be clearly determined which type of vortex shedding is involved in the aeroacoustic process (see [12]). Indeed, two potential sources of vortex shedding are present in such a configuration:…”

“…During the past five decades, many studies on this topic have been conducted either analytically [10], numerically [11] or experimentally with more realistic cold flow apparatus (see [12][13][14]). In addition, for quantifying the effect of the obstacle deflection on flow, some numerical attempts to simulate inhibitors were conducted in a quasi-steady approach [15], but never been compared to experimental data.…”

Self sustained oscillations in Solid Propellant Rocket Motors result from an aeroacoustic phenomenon involving interaction between vortex shedding and acoustics of the chamber. An experimental investigation has been carried out with a cold gas apparatus for acoustic oscillations sustained by vortex shedding. Furthermore, Fluid-Structure interactions have been shown to be of importance when studying pressure oscillations inside Solid Propellant Rocket Motors. Numerical results are compared to preliminary tests undertaken with the use of a non-intrusive measurement technique allowing both displacement and frequency measurements of flexible inhibitors.
