Influence of the Ringwoodite-Perovskite transition on mantle convection in spherical geometry as a function of Clapeyron slope and Rayleigh number [PDF]

open access: yesSolid Earth, 2011
We investigate the influence on mantle convection of the negative Clapeyron slope ringwoodite to perovskite and ferro-periclase mantle phase transition, which is correlated with the seismic discontinuity at 660 km depth.

Investigating double-diffusive natural convection in a sloped dual-layered homogenous porous-fluid square cavity [PDF]

open access: yesScientific Reports
This article investigates natural convection with double-diffusive properties numerically in a vertical bi-layered square enclosure. The cavity has two parts: one part is an isotropic and homogeneous porous along the wall, and an adjacent part is an ...

Local Thermal Non-equilibrium Analysis of Cu-Al2O3 Hybrid ‎Nanofluid Natural Convection in a Partially Layered Porous ‎Enclosure with Wavy Walls [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2023
A numerical study is performed to investigate the local thermal non-equilibrium effects on the natural convection in a two-dimensional enclosure with horizontal wavy walls, layered by a porous medium, saturated by Cu-Al2O3/water hybrid nanofluid.

Focused Penetrative Plumes: A Possible Consequence of the Dissociation Transition of Post‐Perovskite at ∼0.9 TPa in Massive Rocky Super‐Earths

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Based on the standard view of depth‐increasing viscosity in the mantle of rocky planets, convection in the deep mantle of these planets is expected to become less likely as the size of planet increases.

Penetrative Superplumes in the Mantle of Large Super‐Earth Planets: A Possible Mechanism for Active Tectonics in the Massive Super‐Earths

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Recent theoretical studies suggest that the physical and rheological mantle properties in massive rocky planets fall outside conventional behaviors inferred for mantle properties at the Earth's mantle pressures.

ON THE RADIUS ANOMALY OF HOT JUPITERS: REEXAMINATION OF THE POSSIBILITY AND IMPACT OF LAYERED CONVECTION [PDF]

open access: yes, 2015
Observations have revealed that a significant number of hot Jupiters have anomalously large radii. Layered convection induced by compositional inhomogeneity has been proposed to account for the radius anomaly of hot Jupiters.

Shallow cirrus convection – a source for ice supersaturation [PDF]

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2014
The origin and persistence of high ice supersaturation is still not well understood. In this study, the impact of local dynamics as source for ice supersaturation inside cirrus clouds is investigated.

Experimental Investigation on the Effects of Ethanol-Enhanced Steam Injection Remediation in Nitrobenzene-Contaminated Heterogeneous Aquifers

open access: yesApplied Sciences, 2021
Steam injection is an effective technique for the remediation of aquifers polluted with volatile organic compounds. However, the application of steam injection technology requires a judicious selection of stratum media because the remediation effect of ...
