Hydraulic Pressure‐Programmed Molecular Transport in Tough Hydrogels

Advanced Science, EarlyView.
Hydraulic pressure is introduced as a programmable parameter for regulating molecular transport in tough hydrogel membranes. Reversing the pressure direction accelerates or slows transport, tuning characteristic transport times over a 65‐fold range while achieving molecular separation and controlled delivery.

Hydraulic fracture optimization using hydraulic fracture and reservoir modeling in the Piceance Basin, Colorado [PDF]

, 2012
textHydraulic fracturing is an important stimulation method for producing unconventional gas reserves. Natural fractures are present in many low-permeability gas environments and often provide important production pathways for natural gas. The production

Explicit-implicit XFEM for Hydraulic Fracturing with emphasis on transport models on curved crack surfaces

, 2019
The eXtended Finite Element Method (XFEM) has developed to a standard tool in fracture mechanics. The method enriches the approximation space such that inner-element cracks are considered without loss of accuracy.

Simulation of Hydraulically Fractured Wells

IOR 1997 - 9th European Symposium on Improved Oil Recovery, 1997
Fractured wells are frequently encountered in petroleum engineering. They can be hydraulically fractured wells to improve oil production or wells intersecting natural fractures. Due to the presence of the fractures, the flow behaviour and the pressure distribution in the vicinity of the fractured well are complex and the numerical modelling for this ...

Farm labor scarcity and its uneven impacts on crop producers in the United States

American Journal of Agricultural Economics, EarlyView.
Abstract This study is the first to evaluate the impacts of farm labor scarcity on producers in the United States across different crop production systems. Between 2002 and 2017, we disentangle the effects of labor scarcity from the impacts of rising commodity demand, technological change, and supply of other inputs on labor market outcomes.

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

Asia-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.

Research on Diaphragm Pump Fault Diagnosis Method Based on Res‐DCB‐Net

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Nonstationary pressure pulsation signals of diaphragm pumps contain strong background noise and coupled characteristics. This makes it challenging to extract incipient fault features and to decouple faults with similar physical mechanisms. To address these limitations, this paper proposes a spatiotemporal fault diagnosis model named Res‐DCB ...
