New collaboration framework between VKI and DANTEC DYNAMICS

The von Karman Institute and Dantec Dynamics have recently signed an agreement to set up a long-term cooperation on several fields of experimental fluid mechanics. The collaboration aims at the joint development of improved methods and measurement solutions.

Dantec Dynamics (https://www.dantecdynamics.com/) delivers turnkey and customized solutions built on high-end laser optics, imaging, and electronical sensor technologies, and has over 70 years of experience in experimental fluid and solid mechanics.

The first research project aims at developing advanced pre-processing and post-processing tools for Particle Image Velocimetry (PIV), based on data-driven modal analysis. The first benchmark test case, recently measured at the VKI, consists of the flow past a cylinder in accelerating conditions, producing the famous Karman Street in non-stationary conditions. This flow has been analyzed using the recently proposed Multiscale Proper Orthogonal Decomposition (mPOD).
