A Hybrid Generative Reduced-Order Model for the Minimal Flow Unit
Niccolò Tonioni, Lionel Agostini, Marcial Sanchis-Agudo +4
A data-driven reduced-order modelling framework is proposed for wall-bounded turbulent flows to forecast the intermittent near-wall dynamics over extended time horizons from sparse…

VIVALDy: A Hybrid Generative Reduced-Order Model for Turbulent Flows, Applied to Vortex-Induced Vibrations
Niccolò Tonioni, Lionel Agostini, Franck Kerhervé +2
Developing reduced-order models applicable to fluid-dynamics problems involving complex geometries and different flow conditions remains a critical challenge for turbulent flows. T…

Breaking the Reynolds Analogy: Decoupling Turbulent Heat and Momentum Transport via Spanwise Wall Oscillation in Wall-Bounded Flow
Lou Guérin, Cédric Flageul, Laurent Cordier +2
This work investigates spanwise wall oscillation (SWO) as a method to preferentially enhance heat transfer over drag in turbulent channel flow. Direct numerical simulations at $Re_…
