Microcapsules are liquid droplets enclosed by a thin elastic membrane. Being suspended in an external fluid, they undergo large deformations when flowing. Their deformation can be solved numerically, but the resolution of fluid–structure interactions (FSI) requires extremely long computation times. This is major constraint for instance identifying membrane mechanical properties from experimenta...

The turbulent wake generated by a rotor interacting with outlet guide vanes (OGVs) is one of the dominant broadband noise sources in turbofan engine. An accurate representation turbulence therefore important for reliable prediction rotor–OGV interaction noise. This paper presents synthesis method based on spectral proper orthogonal decomposition (POD) that aims to reproduce desired velocity cro...
