Classical Higgs fields on gauge gluon bundles
EPJ Web of Conferences, 2016 Classical Higgs fields and related canonical conserved quantities are defined by invariant variational problems on suitably defined gauge gluon bundles. We consider Lagrangian field theories which are assumed to be invariant with respect to the action of

Characterization of Proppant Flowback in Hydraulic Fracturing Rough Fractures
Energy Science &Engineering, EarlyView.This graphical abstract reveals the proppant flowback mechanism and controlling factors in rough fracture through CFD‐DEM modeling. This study investigates unavoidable proppant flowback during fracturing, which leads to wellbore sand plugging and reduced fracture conductivity. A coupled CFD‐DEM model simulates flowback in rough fracture, revealing that

Energy Science &Engineering, EarlyView.Characteristics of solar radiation protection. ABSTRACT Solar radiation management (SRM) is a geoengineering strategy designed to combat global warming by reflecting sunlight away from Earth, thereby reducing solar heating. While SRM has the potential to lower global temperatures, it's distinct from addressing the root cause of climate change ...

Tangentially biharmonic Lagrangian H-umbilical submanifolds in complex space forms
, 2014 The notion of Lagrangian $H$-umbilical submanifolds was introduced by B. Y. Chen in 1997, and these submanifolds have appeared in several important problems in the study of Lagrangian submanifolds from the Riemannian geometric point of view.

A Semi‐Implicit Numerical Method for Simultaneous Fluid‐Structure Interaction
International Journal for Numerical Methods in Fluids, EarlyView.A one‐dimensional shallow water model is coupled with a floating boat, which is assumed to be in hydrostatic equilibrium with the underlying water. Numerically, a semi‐implicit discretization of the shallow water equations also includes the Archimedes' floating conditions in such a fashion that the boat's vertical position and pitch slope are ...

Clogging Analysis in Drip Irrigation Systems: CFD and DEM Approaches
Irrigation and Drainage, EarlyView.ABSTRACT Clogging represents a critical challenge that undermines the efficiency and sustainability of drip irrigation systems by inducing uneven water distribution and increasing maintenance requirements. In this study, the phenomenon of clogging in drip emitters was investigated via computational fluid dynamics (CFD) in conjunction with the discrete ...
