Spectrally Regularized Latent Flow Matching for Turbulence Generation
Khalid Rafiq, Aditya G. Nair
Latent diffusion and flow matching have emerged as leading approaches for synthetic turbulence generation, yet they systematically under-represent dissipation-range amplitudes. We…
Phase-based analysis and control of low Reynolds number aeroelastic flows
Chathura R. Sumanasiri, Tulsi Ram Sahu, Aditya G. Nair
Flutter in lightweight airfoils under unsteady flows presents a critical challenge in aeroelastic stability and control. This study uncovers phase-localized mechanisms that drive t…
Single-shot prediction of parametric partial differential equations
Khalid Rafiq, Wenjing Liao, Aditya G. Nair
We introduce Flexi-VAE, a data-driven framework for efficient single-shot forecasting of nonlinear parametric partial differential equations (PDEs), eliminating the need for iterat…
Dominant balance-based adaptive mesh refinement for incompressible fluid flows
Gaurav Kumar, Aditya G. Nair
This work introduces a novel adaptive mesh refinement (AMR) method that utilizes dominant balance analysis (DBA) for efficient and accurate grid adaptation in computational fluid d…
