Experimental Study on Backflow Patterns Induced by a Bilateral Groin Pair with Different Spacing

open access: yesApplied Sciences, 2021
Groins are one of the popular manmade structures to modify the hydraulic flow and sediment response in river training. The spacing between groins is a critical consideration to balance the channel-depth and the cost of construction, which is generally ...

Slip Backflow of Polymers in Elastic Fractures for Subsurface Heat Recovery

open access: yesEnergies, 2023
This research delves into the complexities of backflow phenomena in finite-length and flat-walled fractures with elastic walls, specifically focusing on power-law fluids, whose shear-thinning behavior distinguishes them from Newtonian fluids.

On the experiment-friendly formulation of quantum backflow [PDF]

open access: yesQuantum, 2021
In its standard formulation, quantum backflow is a classically impossible phenomenon in which a free quantum particle in a positive-momentum state exhibits a negative probability current. Recently, Miller et al. [Quantum 5, 379 (2021)] have put forward a

Impact of fractures on convective-mixing characteristics of carbon dioxide in saline aquifers

open access: yes工程科学学报
Fractures serve as the main channels for rapid CO2 diffusion and escape during sequestration in saline aquifers. While existing studies have focused on how fracture characteristics and chemical reactions affect CO2 convective mixing, the specific ...

Numerical Analysis of The Effect of Hydrodynamics and Operating Conditions on Biodiesel Synthesis in a Rotor-Stator Spinning Disk Reactor

open access: yesChemical and Process Engineering, 2017
A rotor-stator spinning disk reactor for intensified biodiesel synthesis is described and numerically simulated in the present research. The reactor consists of two flat disks, located coaxially and parallel to each other with a gap ranging from 0.1 mm ...

Research on the Volumetric Efficiency of 2D Piston Pumps with a Balanced Force

open access: yesEnergies, 2020
Axial piston pumps with high rotational speeds are required in many fields to increase the power-to-weight ratio. However, three main sliding friction pairs in the pump restrict the increase in rotational speed.

Demonstrating backflow in classical two beams’ interference

open access: yesNew Journal of Physics, 2022
The well-known interference pattern of bright and dark fringes was first observed for light beams back in 1801 by Thomas Young. The maximum visibility fringes occur when the irradiance of the two beams is equal, and as the ratio of the beam intensities ...

Regulated Ion‐Diffusion Hydrogels for Subtle and Multimodal Temperature‐Strain Sensing in Wound Monitoring

open access: yesAdvanced Functional Materials, EarlyView.
A soft, dual‐channel hydrogel patch enables simultaneous detection of wound temperature and strain by integrating ion‐diffusion‐mediated thermoelectric and resistive sensing. The conformal design maintains stable performance during motion, capturing subtle inflammatory and mechanical changes for continuous wound monitoring.
