Fluid–structure interactions (FSI) on highly flexible structures involve large deformations and require specific techniques for a thorough investigation of the flow field structural deformation. To this purpose, physics-informed method is introduced that allows simultaneous determination fields deformation by using Particle Image Velocimetry (PIV) raw images. The combines apriori knowledge mech...

We investigate the dynamics of elastic microstructures that interact with a fluid flow when subject to thermal fluctuations. We perform analysis to obtain systematically simplified descriptions of the mechanics in the limiting regimes when (i) the coupling forces that transfer momentum between the fluid and microstructures is strong, (ii) the mass of the microstructures is small relative to the...
