A Satellite Analysis: Comparing Two Medicanes

Atmosphere
Morphological features of the Mediterranean Sea basin have recently been precursors to a significant increase in the formation of extreme events, in relation to climate change effects. It happens very frequently that rotating air masses and the formation

Problems of Astrophysical Turbulent Convection: Thermal convection in a layer without boundaries [PDF]

in Procs 2010 CTR Summer Program, P. Moin (ed.), pp. 475-484, Stanford University, 2010, 2011
Thermal convection in fluid layers heated from below are usually realized experimentally as well as treated theoretically with fixed boundaries on which conditions for the temperature and the velocity field are prescribed. The thermal and velocity boundary layers attached to the upper and lower boundaries determine to a large extent the properties of ...

Gravity Waves in the Sun

, 2005
We present numerical simulations of penetrative convection and gravity wave excitation in the Sun. Gravity waves are self-consistently generated by a convective zone overlying a radiative interior.

Atmospheric cooling of freshwater near the temperature of maximum density [PDF]

arXiv
We perform three-dimensional direct numerical simulations of surface-driven convection near the temperature of maximum density $\tilde T_{md}$. A dynamic surface boundary condition couples heat flux through the surface to the induced convection, creating a dynamic equilibrium between the surface water temperature and the convection below.

Deciphering a New Electrolyte Formulation for Intelligent Modulation of Thermal Runaway to Improve the Safety of Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
Diels‐Alder clicks chemistry addresses thermal runaway in lithium‐ion batteries. A thermoresponsive electrolyte with lithium salt in vinylene carbonate (VC) and 2,5‐dimethylfuran (DMFu) operates at room temperature but undergoes Diels‐Alder reactions at high temperatures, enabling a two‐step safety mechanism: a warning phase at ≈100 °C and complete ...

Materializing Convection [PDF]

Architecture and Culture, 2019
This essay uses a physical modeling technique from mechanical engineering, the filling box, as a speculative architectural design tool. In the filling box, dyed salt water is injected into acrylic models submerged within a tank of fresh water, simulating the introduction of cold air into a warm environment or, when mirrored, the introduction of warm ...

Conformally Perforated Shellular Metamaterials with Tunable Thermomechanical and Acoustic Properties

Advanced Functional Materials, EarlyView.
This study introduces Conformally Perforated Shellular Metamaterials (CPSMs), which overcome TPMS design limitations by mapping 2D cellular layouts onto 3D surfaces. CPSMs exhibit enhanced elastic stiffness, thermal conductivity, and acoustic performance compared to intact P‐type shellulars, demonstrating their potential as multifunctional ...
