Numerical Study of Convective Flow of Casson Fluid Through an Infinite Vertical Plate with Induced Magnetic Field

East European Journal of Physics
The present objective is to numerically analyze the induced magnetic field (IMF) effect of an unsteady MHD flow of Casson fluid through two infinite vertical plates. The effect of radiative heat has been scrutinized. Governing non-dimensional PDEs of the

A laboratory-scale experiment and a numerical simulation of unusual spiral plumes in a High-Prandtl-number fluid, links supplementary material

, 2014
We experimentally and numerically investigated the generation of plumes from a local heat source (LHS) and studied the interaction of these plumes with cellular convective motion (CCM) in a rectangular cavity filled with silicon oil at a Prandtl number ...

Near‐Surface Ocean Current and Its Response to Wind Forcing

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Ocean currents near the air‐sea interface are critical for understanding boundary layer processes and advancing coupled models. The near‐surface currents mediate air–sea fluxes and govern the transport of buoyant materials, yet the uppermost meter of the ocean remains sparsely observed and poorly represented in models.

Enhancing Thermal-Hydraulic Modelling in Dual Fluid Reactor Demonstrator: The Impact of Variable Turbulent Prandtl Number

Energies
In response to the growing demand for advanced nuclear reactor technologies, this study addresses significant gaps in thermal-hydraulic modelling for dual fluid reactors (DFRs) by integrating Kays correlation to implement a variable turbulent Prandtl ...

Patterns and bifurcations in low–Prandtl-number Rayleigh-Bénard convection

, 2010
We present a detailed bifurcation structure and associated flow patterns for low–Prandtl-number (P=0.0002, 0.002, 0.005, 0.02) Rayleigh-Bénard convection near its onset.

A Study on the Applicability of the Linear Superposition Principle to Overland Flow Resistance Based on HR‐PIV Technology

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Previous studies have suggested that the linear superposition principle fails for thin‐layer overland flows, yet direct experimental evidence remains scarce. This work adopts high‐resolution particle image velocimetry (HR‐PIV) to measure the 2D flow fields of grain resistance and form resistance in thin‐layer overland flows.

Stationary statistical properties of Rayleigh-Bénard convection at large Prandtl number

, 2006
This is the third in a sequel in our study of Rayleigh-Bénard convection at large Prandtl number. More specifically we investigate if stationary statistical properties of the Boussinesq system for Rayleigh-Bénard convection at large Prandtl number are ...

Evaporation Dynamics From Flowing Water Surfaces

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract In contrast to the wealth of information on evaporation dynamics from placid water surfaces such as lakes and reservoirs, estimating water evaporation from turbulent surfaces of streams remains a challenge. Evidence suggests considerable differences in evaporation rates from flowing water bodies relative to placid surfaces.

Ocean Mixing Regimes Set Heat and Buoyancy Fluxes From the Arctic's Atlantic Water Layer

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Quantifying Arctic Ocean mixing is important for understanding the Arctic climate system. Direct mixing measurements cannot robustly characterize mixing on a pan‐Arctic scale, while indirect estimates based on parameterizations must be made with care; multiple mixing mechanisms including double diffusion, internal wave breaking and molecular ...

Gravity Wave Energy Baselines (∼30–110 km) Established From Lidar Observations at McMurdo (77.84°S, 166.67°E), Antarctica: Energy Dissipation and Constituent Diffusion

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Lidar observations above McMurdo, Antarctica from 2011 to 2024 are used to characterize gravity wave (GWs) potential energies (Ep ${E}_{p}$) in the mesosphere and lower thermosphere (MLT). Alongside characterizations in the middle atmosphere (30–70 km), the GW baselines show dissipation at all altitudes from 30 to 110 km.
