This paper rigorously proves that the Toner-Tu-Swift-Hohenberg equations governing active turbulence possess a finite-dimensional global attractor with Lyapunov dimension estimates consistent with heuristic predictions, while also validating these theoretical bounds through pseudospectral numerical simulations in two dimensions.
This paper proposes a topology optimization method for designing passively moving rigid bodies in unsteady fluid flows by coupling rigid-body dynamics with lattice kinetic fluid equations and applying an adjoint-based sensitivity analysis to optimize shapes for translational and rotational motions.
This paper presents a validated experimental facility and image-based methodology using dyed water and bi-exponential modeling to accurately measure water depth in three-dimensional dam-break flows, with results confirmed by high statistical repeatability and independent volume estimates.
This study reveals that spontaneous electrostatic charging, driven by the plasticity of the epicuticular wax layer, fundamentally alters droplet dynamics on living leaves by generating forces strong enough to significantly slow water movement, challenging the traditional view of leaves as electrically neutral substrates.
This paper presents a study using ANSYS Discovery turbulent flow simulations to analyze and optimize the hull geometry of the N.E.O.N.-Bridge autonomous segment, aiming to enhance its stability, structural rigidity, and hydrodynamic performance under dynamic water conditions.
This study uses high-resolution numerical simulations to reveal that while turbulent mixing layers grow super-diffusively, increasing salinity induces a transition to diffusive growth near the ice-ocean interface via a regulating boundary layer, thereby confining double-diffusive effects to the interface and highlighting limitations in fixed-threshold oceanographic diagnostics.
This study presents numerical simulations and experimental measurements demonstrating that the collapse of a hemicatenoid soap film bounded by a solid wall is driven by viscous dissipation within surface Plateau borders, a mechanism distinct from the inertia-dominated collapse of free catenoids and relevant to bubble fragmentation in confined geometries.
This paper proposes and validates scaling laws for undulatory swimming that reveal a crossover in tail beat frequency behavior around 0.5–1 m, where smaller animals are limited by biological muscle constraints while larger animals are governed by fluid-swimmer interactions, ultimately predicting a maximum swimming speed of 5–10 m/s to prevent cavitation.
This study leverages a biomimetic robotic swimmer combined with machine learning and intuitive models to identify optimal control strategies for maximizing thrust production, offering a practical, model-free implementation for autonomous underwater locomotion that bridges fluid dynamics, robotics, and biology.
This study experimentally demonstrates that the drainage dynamics of vertical rectangular soap films are self-similar and universal, governed by a single physical scalar that unifies thickness profiles across various conditions and offers new insights into marginal regeneration.
