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…
End-to-end data-driven prediction of urban airflow and pollutant dispersion
Nishant Kumar, Franck Kerhervé, Lionel Agostini +1
Climate change and the rapid growth of urban populations are intensifying environmental stresses within cities, making the behavior of urban atmospheric flows a critical factor in…
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_…
