International audience; Transpired boundary layers are of major interest for many industrial applications. Although well described, there is no turbulence model specifically dedicated to the prediction of boundary layers for both blowing and suction

An experimental campaign dedicated to the characterization of the wall-normal velocity correlations in a zero pressure gradient turbulent boundary layer was performed. A double set of laser Doppler velocimetry (LDV) benches were used to access two-po

International audience; For vibro-acoustic applications, a turbulent wall pressure fluctuations model was derived. The model is based on the resolution of the Poisson equation. The pressure is characterized in time and space through its spectrum in t

Laminar-turbulent transition of an experimental configuration representative of the flow in Solid Rocket Motors is investigated using Large Eddy Simulation. The specific instability of this flow is reproduced and a turbulent region is recovered, usin

This paper presents a characterization of the laminar-turbulent transition in cold flow setup, representative of the flow in a solid rocket motor. Recent developments based on a linear stability analysis of this particular flow have highlighted the e

Large solid rocket motors exhibit undesirable thrust oscillations during their firing. These oscillations are connected to inflow pressure fluctuations induced by flow instabilities. Recent classical hydrodynamic stability calculations have pointed o
