The interaction of longitudinal vortex pairs with a turbulent boundary layer
Journal of Fluid Mechanics, 2022 In this study, we demonstrate an efficient approach to investigating the interaction of vortex pairs on a turbulent boundary layer. Our aim is to assess how vortex characteristics impact the downstream flow. Wall-modelled large eddy simulations are used together with an inlet defined by a Batchelor vortex model superimposed on a turbulent boundary ...

Impact of Disorder on Microscopic Superconducting and Normal‐State Responses in a Kagome Metal
Advanced Functional Materials, EarlyView.Using depth‐resolved, field‐ and pressure‐dependent μSR$\umu{\rm SR}$ measurements, we show that disorder in Ta‐doped KV3Sb5 drives a crossover from nodal to nodeless superconductivity while strongly modifying the normal‐state magnetic response. Our results reveal that disorder affects superconductivity and magnetism in fundamentally different ways ...

Experimental Study on Heat Transfer Characteristics of the Delta Winglets with V-shaped Array
Zhileng xuebao, 2015 In the range of Re = 4800~10200, the experiment was made to investigate the heat transfer characteristics of two rows of the delta winglets arrayed in V shape at the back side of the round tube in the rectangular channel.

Advanced Functional Materials, EarlyView.Sea cucumber mutable collagenous tissue (MCT) is a remarkable collagen‐based material which can rapidly undergo large changes in stiffness through transiently bound effector proteins. Here, we investigate the hierarchical structure and mechanical response of MCT from Cucumaria frondosa across length scales with a wide range of methods, also exploring ...

Advanced Healthcare Materials, EarlyView.Gellan gum fluid gel (FG) enables controlled ocular delivery of mesenchymal stromal cell (MSC)‐derived extracellular vesicles (EV). Its shear‐thinning, solid‐liquid‐solid rheology ensures prolonged ocular retention. Sustained MSC‐EV release (∼18% in 6 hrs) supports effective EV ocular delivery.

STABILITY MECHANISM AND CONTROL OF LONGITUDINAL VORTEX STREETS
PROCEEDINGS OF HYDRAULIC ENGINEERING, 1993 Boundary effects on the stability of the street of longitudinal vortices with their alternately changing direction are investigated by using the vortex filament model. The analysis shows that the longitudinal vortex street is unstable to a infinitesimal disturbance in both the infinite and the semi-infinite regions over a flat bed, whereas it is stable
