This paper presents a physics-informed spatiotemporal surrogate model that combines convolutional neural networks and LLM-inspired recurrent architectures with conformal prediction to efficiently and physically accurately simulate turbulent Rayleigh-Bénard convection.
This paper presents a self-consistent numerical model in polar geometry demonstrating that internal gravity waves generated by a convective core can drive periodic reversals in the azimuthal mean flow of a stably-stratified stellar envelope, analogous to the Earth's Quasi-Biennial Oscillation.
This paper experimentally investigates how vertical harmonic excitation induces parametric sloshing in a horizontally oriented cylindrical tank, using an Augmented-state Extended Kalman Filter to provide real-time identification of the resulting rapid increases in heat and mass transfer and the subsequent thermal destratification.
Using a hybrid RANS/LES approach, this study characterizes the three-dimensional evolution of stall cells over an airfoil, revealing how spanwise separation variations and Crow-type instabilities between vortex tubes drive complex vorticity dynamics and a previously unreported linear rotation of spanwise velocity structures.
This paper develops a first-principles analytical model that explains the formation and saturation of spanwise-periodic stall cells by treating them as a Crow-type instability arising from the interaction between counter-rotating vortex tubes.
This paper presents a second-order accurate, fixed-grid sharp-interface numerical method to solve the three-phase Stefan problem in spherical coordinates, demonstrating that kinetic energy terms significantly influence the phase change behavior of nanoparticles compared to larger particles.
This paper demonstrates that in gentle-slope debris flows, small-amplitude dispersive pulses can be modeled using a Korteweg-de Vries (KdV) reduction, identifying them as a regime-specific mechanism that complements roll-wave dynamics in facilitating long-runout mobility.
This study investigates the stability and dynamics of gravity-driven thin liquid films on conical surfaces by developing a Benney-type equation and a low-dimensional model, revealing that while streamwise curvature influences stability, the wave dynamics primarily depend on radial distance and can be closely approximated by flat-plate models through local parameter substitution.
This study uses high-order large-eddy simulations to demonstrate that steady viscous inflow profiles more accurately represent supersonic jet near-field characteristics and velocity fluctuations compared to inviscid profiles, while also providing a high-fidelity, open-access database for the scientific community.
This study utilizes large-scale 3T vertical Magnetic Resonance Imaging (MRI) and Computational Fluid Dynamics (CFD) to characterize and validate 3D liquid flow fields within additively manufactured TPMS structures, revealing that Schwarz-Diamond geometries significantly enhance lateral mixing compared to Gyroid structures.
