This study utilizes direct numerical simulations and theoretical analysis to demonstrate that realistic no-slip end-wall boundary conditions in Taylor-Couette flow induce multiple stable states with pronounced hysteresis, distinct transition sequences, and altered angular momentum transport compared to periodic conditions.
Through direct numerical simulations of two-dimensional isothermal compressible turbulence, this study reveals that while pair-dispersion halving-time statistics exhibit universal multifractal scaling, doubling-time statistics are non-universal and depend on the nature of the stirring force and Mach number, with significant implications for astrophysical gas transport and mixing.
This study demonstrates that accurately capturing both laminar and turbulent regions over a wing using Wall-Modeled Large-Eddy Simulation (WMLES) requires a hybrid grid resolution strategy combined with the introduction of unsteady disturbances to trigger transition, as standard uniform grids fail to satisfy the conflicting near-wall resolution requirements of both flow regimes.
This paper evaluates the effectiveness of tool-using coding agents in automating OpenFOAM CFD workflows, demonstrating that prompt-guided configurations and advanced language models significantly improve task completion rates for both tutorial-based and complex geometry simulations.
This study experimentally demonstrates that multi-droplet arrays exhibit longer evaporation lifetimes than isolated droplets due to a vapor-shielding effect, a phenomenon that increases with droplet density but diminishes at higher temperatures due to natural convection.
This paper demonstrates through numerical simulations that the interaction between near-inertial waves and submesoscale currents at ocean fronts creates an asymmetry in vertical motion—driven by strong vertical shear—that enables net vertical transport of biogeochemical tracers.
Using structure-resolved direct numerical simulations, this study identifies two distinct wake regimes—weakly stratified and strongly stratified—revealing that deep-water offshore wind sites trigger large-scale internal waves that facilitate far-field energy propagation and explain previously enigmatic field observations.
This paper derives analytical solutions for the hydrodynamic flow fields and mobility tensors induced by localized torques in wedge-shaped geometries using the Fourier-Kontorovich-Lebedev transform, demonstrating that the broken spatial symmetry causes particles to undergo both rotational and translational motion.
This paper explores the catastrophic consequences of a world without viscosity, illustrating how the loss of fluid friction would dismantle essential systems ranging from mechanical engineering and aviation to biological life and planetary climates.
This study validates an analytic momentum availability model using large-eddy simulation data and proposes an extension to its linearized version to improve accuracy in cases involving high atmospheric boundary-layer heights or strong Coriolis forcing.
