A numerical study of two-phase flow with dynamic capillary pressure using an adaptive moving mesh method [PDF]

open access: yes, 2016
Motivated by observations of saturation overshoot, this paper investigates numerical modeling of two-phase flow incorporating dynamic capillary pressure.

Turbulent snow transport and accumulation: New reduced‐order models and diagnostics

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Our new reduced‐order models of snow particle transport provide high‐fidelity calculations of snow accumulation in turbulent flows at significantly reduced computational costs. Additional accumulation diagnostics from the reduced‐order model predict complex patterns of particle concentration in turbulent boundary layers via coherent flow structures in ...

Tectonic Controls on Late Paleozoic Shale Gas Preservation in Western Shandong, China

open access: yesJournal of Marine Science and Engineering
Based on structural geology, petrology, shale gas geology, and basin modeling, this study investigates the characteristics of tectonic evolution and sedimentary responses in Western Shandong since the Late Paleozoic.

PARTY‐STATE URBANISM: Coevolution of Local State Capacity and Strategic Alliances in Shenzhen

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract What is distinct about Chinese urban governance? Classic theories predict that when the central state retreats from resource allocation, capacity‐strained local governments must form alliances with non‐state actors, thereby diluting state power. In China, however, state power remains dominant despite decentralization.

Gas diffusivity‐based characterization of aggregated soils linking to methane migration in shallow subsurface

open access: yesVadose Zone Journal, 2021
Methane transport in soil is primarily affected by soil physical conditions such as soil texture and soil structure, soil moisture, soil‐gas diffusivity, permeability, and soil temperature.

GH-3PAD – a new numerical solver for multiphase transport in porous media - new insights on gas hydrate and free gas co-existence [PDF]

open access: yes, 2013
Gas Hydrate-3 Phase Advanced Dynamics (GH-3PAD) code has been developed to study the geophysical and biochemical processes associated with gas hydrate as well as free methane gas formation and dissolution in marine sediments.

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

open access: yesBoreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Metal sources for the Katanga Copperbelt deposits (DRC) insights from Sr and Nd isotope ratios [PDF]

open access: yes, 2014
The ore deposits of the Central African Copperbelt formed during a multiphase mineralisation process. The basement underlying the Neoproterozoic Katanga Supergroup that hosts the ore, demonstrates the largest potential as metal source.

Authoring Terrestrial Planets with Diffusion Models

open access: yesComputer Graphics Forum, EarlyView.
Abstract To support the design and subsequent generation of terrestrial planets for use in the creative media, we propose a solution that employs a generative model trained on satellite data from planetary bodies with a defined solid surface, such as the Earth and Mars.

The stability of a rising droplet: an inertialess nonmodal growth mechanism [PDF]

open access: yes, 2015
Prior modal stability analysis (Kojima et al., Phys. Fluids, vol. 27, 1984) predicted that a rising or sedimenting droplet in a viscous fluid is stable in the presence of surface tension no matter how small, in contrast to experimental and numerical ...
