New SINDy framework extracts Rayleigh-Taylor instability dynamics from data

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new data-driven framework using Sparse Identification of Nonlinear Dynamics (SINDy) to extract equations describing Rayleigh-Taylor instability (RTI). This method accurately captures the overshoot behavior and reacceleration stages of bubble and spike velocities, outperforming traditional potential-flow and buoyancy-drag models. The framework is effective across various Atwood numbers and initial amplitudes, offering a complementary approach for understanding interfacial instabilities. AI

IMPACT This research offers a novel data-driven approach to modeling complex physical phenomena, potentially influencing how scientific simulations and predictions are developed.

    Extracting Single-Mode Rayleigh--Taylor Instability dynamics from data via SINDy

    arXiv:2611.07666v1 Announce Type: cross Abstract: Rayleigh-Taylor instability (RTI) is of fundamental importance in fields such as inertial confinement fusion and supernova explosions, and its evolution is commonly described by potential--flow theory and buoyancy--drag models. Ho…
