SUMMARY:Séminaire Mécanique d'Orsay
DESCRIPTION:In this talk\, we will discuss how data assimilation methodolog
 ies may enable combining experimental\, high-fidelity and low-fidelity num
 erical simulations\, and thus achieve complementarity amongst these approa
 ches to study and characterize aerodynamic flows. From the experimentalist
 ’s point of view\, it will be illustrated how data assimilation may be u
 sed to increase the spatio/temporal resolution of experimental data and in
 fer non-measured quantities\, considering in particular the case of optica
 l techniques such as Particle Tracking Velocimetry. From a more modeling-o
 riented perspective\, we will consider the application of data assimilatio
 n to enhance Reynolds-Averaged Navier-Stokes (RANS) models based on veloci
 ty or parietal pressure measurements. Based on the so-calibrated models\, 
 stability and resolvent analysis may then be performed to predict detailed
  flow features that are difficult to characterize from experiments or simu
 lations alone. Such an approach will be applied in particular to the chara
 cterization of stall cells for the flow around a NACA4412 profile at a cho
 rd-based Reynolds number of Re=3.5x10^5.
