This study unifies the impact dynamics of liquid drops and elastic beads by employing direct numerical simulations of a generic viscoelastic sphere to demonstrate how varying elasticity and relaxation time parameters continuously bridges the gap between Wagner's liquid theory and Hertz's solid theory, revealing a smooth transition through distinct force-scaling regimes.
This paper presents the computational and experimental optimization of a multifunctional magnetic milli-spinner, demonstrating that its enhanced structural design enables record-breaking swimming velocities in blood-mimicking fluids, thereby establishing a robust untethered platform for navigating high-flow, tortuous vasculature to treat vascular diseases.
This paper presents a compact, low-cost, single-mirror schlieren imaging system utilizing water immersion that reduces the system's footprint by 25% and minimizes mirror artifacts to enable high-sensitivity flow visualization in both water and air.
This paper proposes a closed-loop control framework based on a parametric reduced-order model that successfully suppresses vortex shedding in the gap and wake of tandem cylinders at low Reynolds numbers using limited sensing and volumetric forcing.
This paper presents a hierarchical SwinV2-UNet Vision Transformer framework that leverages multimodal, multi-fidelity CFD data to accurately predict spatiotemporal fluid flow evolution and reconstruct unobserved fields in complex energy systems, such as high-pressure gas injection in reciprocating engines.
This paper introduces an optimized wave-appropriate reconstruction method for compressible flows that systematically minimizes the acoustic upwind parameter for robust stability across regimes and employs a rank-1 entropy wave correction to eliminate explicit contact-discontinuity detectors, thereby improving accuracy and reducing computational cost.
This paper introduces a simplified nanomechanical platform that directly detects electron vortices by measuring the torque-induced vibrations of a suspended resonator containing a circular cavity, thereby establishing nanomechanics as a powerful tool for studying electron hydrodynamics and viscosity.
This study combines experiments, simulations, and analytical modeling to demonstrate that pore-scale disorder in porous media accelerates fluid stretching and mixing by localizing deformation near solid boundaries, leading to quadratic rather than linear growth in mean stretching over time.
This paper establishes a unifying framework for understanding the sedimentation dynamics of helical ribbons at low Reynolds numbers, demonstrating how minute center-of-mass offsets break geometric symmetries and trigger bifurcations from complex limit cycles to simple attracting states via a defined alignment bifurcation surface.
This paper provides a rigorous mathematical proof, supported by numerical simulations, that a concentrated vortex blob in a 2D inviscid fluid moves along the gradient of an underlying non-constant vorticity field, offering a unique Lagrangian explanation for the aggregation of same-sign vortex structures and extending this result to nearly vertical vortex filaments in 3D domains.
