Direct observations of melting, freezing, and ocean circulation in an ice shelf basal crevasse

P Washam, JD Lawrence, CL Stevens, CL Hulbe… - Science …, 2023 - science.org
Ocean conditions near the grounding zones of Antarctica's ice shelves play a key role in
controlling the outflow and mass balance of the ice sheet. However, ocean observations in …

[HTML][HTML] Laboratory experiments on ice melting: a need for understanding dynamics at the ice-water interface

AL McCutchan, BA Johnson - Journal of Marine Science and …, 2022 - mdpi.com
The ice-ocean interface is a dynamic zone characterized by the transfer of heat, salinity, and
energy. Complex thermodynamics and fluid dynamics drive fascinating physics as ice is …

Morphology evolution of a melting solid layer above its melt heated from below

R Yang, CJ Howland, HR Liu, R Verzicco… - Journal of Fluid …, 2023 - cambridge.org
We numerically study the melting process of a solid layer heated from below such that a
liquid melt layer develops underneath. The objective is to quantitatively describe and …

Ice melting in salty water: layering and non-monotonic dependence on the mean salinity

R Yang, CJ Howland, HR Liu, R Verzicco… - Journal of Fluid …, 2023 - cambridge.org
The presence of salt in seawater strongly affects the melt rate and the shape evolution of ice,
both of utmost relevance in ice–ocean interactions and thus for the climate. To get a better …

Dissolution-driven propulsion of floating solids

M Chaigne, M Berhanu… - Proceedings of the …, 2023 - National Acad Sciences
We show that unconstrained asymmetric dissolving solids floating in a fluid can move
rectilinearly as a result of attached density currents which occur along their inclined …

Yardangs sculpted by erosion of heterogeneous material

S Boury, S Weady, L Ristroph - Proceedings of the National Academy of …, 2024 - pnas.org
The recognizable shapes of landforms arise from processes such as erosion by wind or
water currents. However, explaining the physical origin of natural structures is challenging …

Shape effect on solid melting in flowing liquid

R Yang, CJ Howland, HR Liu, R Verzicco… - Journal of Fluid …, 2024 - cambridge.org
Iceberg melting is a critical factor for climate change. However, the shape of an iceberg is an
often neglected aspect of its melting process. Our study investigates the influence of different …

Double-diffusive transport in multicomponent vertical convection

CJ Howland, R Verzicco, D Lohse - Physical Review Fluids, 2023 - APS
Motivated by the ablation of vertical ice faces in salt water, we use three-dimensional direct
numerical simulations to investigate the heat and salt fluxes in two-scalar vertical …

Laboratory experiments of melting ice in warm salt-stratified environments

JK Sweetman, CJ Shakespeare, KD Stewart… - Journal of Fluid …, 2024 - cambridge.org
Melting icebergs provide nearly half of the total freshwater flux from ice shelves to the ocean,
but the availability of accurate, data-constrained melting rate parametrisations limits the …

How fluid-mechanical erosion creates anisotropic porous media

NJ Moore, J Cherry, SH Chiu, BD Quaife - Physica D: Nonlinear …, 2023 - Elsevier
Using a Cauchy integral formulation of the boundary integral equations, we simulate the
erosion of a porous medium comprised of up to 100 solid bodies embedded in a two …
