Topography generation by melting and freezing in a turbulent shear flow

Louis-Alexandre Couston et al.

Summary: We conducted an idealized numerical study on melting and freezing solid adjacent to turbulent, buoyancy-affected shear flow. The results show that channels generated at the fluid-solid interface align with the direction of the mean flow and vary significantly under different density stratification.

Dynamic flows create potentially habitable conditions in Antarctic subglacial lakes

Louis-Alexandre Couston et al.

Summary: Physical conditions within subglacial lakes in Antarctica are crucial for evaluating microbial life, with Earth's geothermal flux providing efficient mixing support. Most lakes exhibit vigorous turbulent vertical convection, aiding suspension of particulates, and enabling nutrient and oxygen distribution. Caution is needed when using accreted ice analysis as a proxy for water sampling in lakes beneath a thin ice cover.

The convective Stefan problem: shaping under natural convection

Samuel S. Pegler et al.

Summary: This theoretical analysis of melting or dissolving bodies in ambient fluid presents new phenomena such as the emergence of fundamental similarity solutions, asymptotic transitions, and the conditions for sharp versus blunted tips. The study reveals that the tips of certain shapes, including initially rectangular bodies, continuously sharpen over time, while tips of other shapes, like initially conic bodies, blunt. These findings provide foundational knowledge of buoyancy-driven fluid sculpting with implications for natural and industrial applications.

Universal properties of penetrative turbulent Rayleigh-Benard convection

Qi Wang et al.

Summary: This study focuses on the penetrative turbulence that occurs in a convectively unstable fluid layer and penetrates into an adjacent, originally stably stratified layer, using the canonical Rayleigh-Benard geometry as an example. The key control parameter is the density inversion parameter theta(m), while the key response parameters are the relative mean midheight temperature theta(c) and the overall heat transfer (Nusselt number Nu). Results show that these parameters' universal dependencies are solely determined by the density inversion parameter theta(m), and a specific relationship exists when theta(m) is below a certain threshold.
