Anisotropy in Dry‐Type Valve‐Side Bushings of Converter Transformer: Phenomena and Effects
High Voltage, EarlyView.ABSTRACT The safe and stable working of dry‐type valve‐side bushings, important components of converter transformers, is essential. In recent years, poor design has led to several core breakdown, flashover and cracking failures. The bushing cores, composed of crepe paper and aluminium foil, exhibit significant anisotropic physical properties due to its

Thermo‐Hydrodynamic Processes of Microparticles in Fractures: A CFD–DEM Approach
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 10, Page 4230-4246, July 2026.ABSTRACT Controlling fracture permeability plays a critical role in subsurface energy applications, particularly in geothermal energy production and enhanced carbon sequestration, where regulating fluid flow is essential. The use of microcapsules has become a promising solution to enhance fracture permeability by providing a controlled sealing ...

On the Cell Broadening of Mesoscale Cellular Convection in a Well‐Mixed Boundary Layer
Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.Abstract Understanding what controls the horizontal scale of mesoscale cellular convection is central to explaining cloud self‐organization and its radiative impacts. Using a hierarchy of large‐eddy simulations, we investigate cell broadening in a well‐mixed boundary layer by isolating the roles of radiation, cloud microphysics, and water vapor.

Turbulence modelling of turbulent buoyant jets and compartment fires [PDF]
, 2001 Turbulent buoyant jets are a major feature in fire hazards. The solution of the Reynolds Averaged Navier-Stokes (RANS) equations through computational fluid dynamic (CFD) techniques allow such flows to be simulated.

Large Eddy Simulations of the Atmospheric Boundary Layer Over Satellite‐Sensed Sea Ice Maps
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.Abstract Surface heterogeneity in the marginal ice zone (MIZ) causes multiscale secondary atmospheric circulations that are challenging to model or observe. The absence or inadequate representation of these circulations in ocean‐atmosphere exchange schemes in climate models is partially responsible for the underestimation of Arctic sea ice loss ...

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract The atmosphere and ionosphere form a vertically coupled system in which disturbances in the lower atmosphere can modulate ionospheric variability. Using reanalysis data, ground‐based GNSS observations, and COSMIC‐2 profiles, we investigate gravity waves (GWs) generation and upward coupling during a southwest vortex (SWV) event over the Tibetan
