Reconstruction of irregular flow dynamics around two square cylinders from sparse measurements using a data-driven algorithm
Flavio Savarino, George Papadakis
We propose a data-driven algorithm for reconstructing the irregular, chaotic flow dynamics around two side-by-side square cylinders from sparse, time-resolved, velocity measurement…
On the role of laminar/turbulent interface on energy transfer between scales in bypass transition
Hanxun Yao, George Papadakis
We investigate the role of laminar/turbulent interface in the interscale energy transfer in a boundary layer undergoing bypass transition, with the aid of the Karman-Howarth-Monin-…
Sensitivity-enhanced generalized polynomial chaos for efficient uncertainty quantification
Kyriakos D. Kantarakias, George Papadakis
We present an enriched formulation of the Least Squares (LSQ) regression method for Uncertainty Quantification (UQ) using generalised polynomial chaos (gPC). More specifically, we…
On the structure of Vorticity and Turbulence Fields in a separated flow around a finite wing; analysis using Direct Numerical Simulation
Juan Carlos Bilbao-Ludena, George Papadakis
We investigate the spatial distributions and production mechanisms of vorticity and turbulent kinetic energy around a finite NACA 0018 wing with square wingtip profile at $Re_c=10^…
Sensitivity analysis of chaotic systems using a frequency-domain shadowing approach
Kyriakos D. Kantarakias, George Papadakis
We present a frequency-domain method for computing the sensitivities of time-averaged quantities of chaotic systems with respect to input parameters. Such sensitivities cannot be c…
