A study of vertical exchange between surface water and groundwater around the banks of Baiyangdian Lake

open access: yesShuiwen dizhi gongcheng dizhi, 2021
Interaction between surface water and groundwater has always been a hot topic in hydrogeological researches. Previous studies focused on the hyporheic zone of rivers, but the hypolentic zone of lakes with relatively static water bodies was seldom ...

A Pollen‐Enhanced Bionic Mechanoreceptor Induced by Asymmetric Ionic Convection in Hydrogel for Sensory‐Augmented Prostheses

open access: yesAdvanced Science, EarlyView.
This work proposed a pollen‐enhanced bionic mechanoreceptor based on ionic convection. Leveraging the ion anchoring effect of the pollen particle, the output performance could be ∼12 times higher than the original state. By employing deep learning models as AI brains, the feasibility of a sensory‐augmented prosthesis consisting of a pollen‐enhanced ...

Radiative Hybrid Nanofluid Flow Over a Porous Riga Surface: A Fuzzy–ANN Modeling Approach

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study proposes a fuzzy–ANN model to investigate the nonlinear thermal transport in a tangent hyperbolic (Tanh) hybrid nanofluid flow past a porous Riga surface, considering the effects of Rosseland diffusion, chemical reactions, and internal volumetric heating.

Numerical Study of MHD Hybrid Nanofluid Flow With Multiple Slip Effects Over a Variable Porous Stretching Surface

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This work discusses the thermal performance of magnetized hybrid nanofluid flow over a variable porous stretchable surface, emphasizing the underlying physical mechanisms governing heat and mass transfer. The Cattaneo–Christov flux model is used in place of Fourier's and Fick's laws to incorporate relaxation effects, ensuring a more realistic ...

Study on Non-darcy Seepage Mechanism of Gas Migration in Coal

open access: yesMeikuang Anquan, 2020
Under different confining pressures, gas seepage tests are carried out, and these tests are used to discuss gas seepage mechanism in coal. The tested and theoretical results show that under different confining pressures, gas seepage laws are consistent ...

Universal Relationship Between Viscous and Inertial Permeability of Geologic Porous Media

open access: yesGeophysical Research Letters, 2019
Fluid flow through geologic porous media is represented by Darcy's law and its inertial and nonlinear extension, the Forchheimer equation. These relationships equate the product of the driving potential gradient and phenomenological coefficients ...

HESS Opinions: Linking Darcy's equation to the linear reservoir [PDF]

open access: yesHydrology and Earth System Sciences, 2018
In groundwater hydrology, two simple linear equations exist describing the relation between groundwater flow and the gradient driving it: Darcy's equation and the linear reservoir.

No other choice: The fracturing of reflexivity in families' pathways into (non‐)elective home education in England

open access: yesBritish Educational Research Journal, EarlyView.
Abstract In England, education is compulsory, but schooling is not: it is legal for families to home educate their children. This form of education is officially termed by the Department for Education as ‘Elective Home Education’. As this designation implies, many families home educate as a positive and preferential ‘choice’.
