Uncertainty quantification of time-average quantities of chaotic systems using sensitivity-enhanced polynomial chaos expansion
George Papadakis, Kyriakos D. Kantarakias
We consider the effect of multiple stochastic parameters on the time-average quantities of chaotic systems. We employ the recently proposed \cite{Kantarakias_Papadakis_2023} sensit…

An Overset Algorithm for Multiphase Flows using 3D Multiblock Polyhedral Meshes
Spiros Zafeiris, George Papadakis
In this study, we present a parallel topology algorithm with a suitable interpolation method for chimera simulations in CFD. The implementation is done in the unstructured Finite V…

Investigation of Submergence Depth and Wave-Induced Effects on the Performance of a Fully Passive Energy Harvesting Flapping Foil Operating Beneath the Free Surface
Nikolaos Petikidis, George Papadakis
This paper investigates the performance of a fully passive flapping foil device for energy harvesting in a free surface flow. The study uses numerical simulations to examine the ef…
