International Journal for Numerical Methods in Fluids, Volume 98, Issue 5, Page 557-577, May 2026.This study investigates the impact of uncertain parameters on Navier–Stokes equations coupled with heat transfer using the Intrusive Polynomial Chaos Method (IPCM). Sensitivity equations are formulated for key input parameters, such as viscosity and thermal diffusivity, and solved numerically using the Finite Element‐Volume method.

Coherent structures in boundary layers of Rayleigh-Benard convection
, 2004 A coherent structure is revealed experimentally by a dyeing technique in the boundary layer of Rayleigh-Benard convection in water. Dye accumulates in streaks aligned with the mean flow.

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Drizzle initiation through the collision and coalescence of cloud droplets plays a crucial role in warm cloud precipitation. Recent theoretical studies suggest that the influence of collisional growth on the droplet size distribution can be quantified by a non‐dimensional drizzle number (Dz).

Patterns in spherical Rayleigh-Benard convection: A giant spiral roll and its dislocations
, 2002 Thermal convection in a moderately thin spherical fluid layer in the presence of spherically symmetric gravity, spherical Rayleigh-Benard convection, is investigated through fully three-dimensional numerical simulations. A steady spherical pattern in the

Scaling of Latitude‐Dependent Heat Transport in Geostrophic Convection
Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract Latitudinal variations in heat transport shape the thermal and magnetic evolution of rapidly rotating planets, stars, and icy moons. Although global simulations have revealed strong equatorial–polar contrasts, a predictive scaling theory has been lacking.

Fast and Slow Signal Propagation in Abiotic Polypeptide Assemblies
ChemBioChem, Volume 27, Issue 6, 27 March 2026.Proteinoid microspheres formed by thermal polymerization of amino acids exhibit spontaneous electrical potential fluctuations without genetic material, membranes, or ion channels. Multi‐electrode recordings and electron microscopy reveal composition‐dependent voltage oscillations, long‐term drifts, and correlated signals across electrodes.

The Barrel of Ilmenau: A large-scale convection experiment to study dust devil-like flow structures.
Meteorologische Zeitschrift, 2021 We present an experimental facility for the validation of numerical simulations on atmospheric dust devils in a controlled laboratory experiment. Dust devils are atmospheric air vortices with a vertical axis, and are formed by intense solar radiation and
