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.

Transient thermal modelling of green anode cooling in the aluminium industry

The Canadian Journal of Chemical Engineering, Volume 104, Issue 8, Page 4120-4134, August 2026.
Summary of the methodology. Abstract Anodes, which are used in electrolytic aluminium production, are made by mixing dry aggregate (petroleum coke, rejected anodes, and butts) with coal tar pitch, compacting the resulting paste (green anode), and baking (baked anode). After compaction, the anodes are cooled to maintain their structural integrity before

Numerical modeling of thermophoresis and Brownian with heat transfer in shear-rate-dependent fluid: The finite element simulations

Case Studies in Thermal Engineering
This article discusses the simultaneous influence of thermophoresis, Brownian motion, and the dispersion of nanoparticles on thermal enhancement in non-Newtonian fluid existing over a surface stretching with non-uniform velocity.

Formation and Stability of Solid Noses During Float Zone Silicon Growth

Crystal Research and Technology, Volume 61, Issue 8, August 2026.
The float zone method is a well‐established way of producing some of the highest purity silicon crystals in the world. However, a common problem is the formation of tiny silicon spikes (called noses) on the feed rod during induction melting. This paper presents a quantitative model of these noses based on the balance between thermal radiation and ...

MHD Heat Transfer Enhancement in TiO2‐Fe3O4/Water Hybrid Nanofluid Over a Porous Stretching/Shrinking Surface With Suction/Injection and Heat Source Effects

Engineering Reports, Volume 8, Issue 8, August 2026.
Magnetohydrodynamic flow of TiO2‐Fe3O4/water hybrid nanofluid over a porous stretching/shrinking surface enhances heat transfer under Joule heating and radiation effects. Thermal performance improves with nanoparticle concentration and Eckert number, while suction reduces heat transport, highlighting its potential for advanced industrial cooling ...

Transient Conjugate MHD Flow With Variable Thermal Conductivity: A CFD to ANN Study

Engineering Reports, Volume 8, Issue 8, August 2026.
A star‐shaped obstacle inside a hexagonal cavity alters fluid flow and heat transfer under magnetic fields. Simulations and ANN predictions reveal that magnetic strength and material properties control cooling efficiency, supporting smarter designs for real‐time thermal management.

Modeling and Analysis of Nonlinear Radiative and Electromagnetic Effects With Second‐Order Slip in Unsteady Hybrid Nanofluid Flow Past a Porous Stretching Surface

Engineering Reports, Volume 8, Issue 8, August 2026.
The current work examines the dynamics of the stagnation point flow of an unsteady hybrid nanofluid (Fe2O3–Cu/H2O) across an inclined porous stretching surface. It considers heat transfer, second‐order slip, electrical field, heat source/sink, mixed convection, and magnetic field effects, as well as linear and nonlinear radiation.

Computational Investigation of MHD Radiative Flow of Shape‐Dependent Al2O3$$ A{l}_2{O}_3 $$ and Fe3O4$$ F{e}_3{O}_4 $$ Nanofluids in A Semi‐Porous Channel

Engineering Reports, Volume 8, Issue 8, August 2026.
A computational study of unsteady MHD radiative nanofluid flow in a semi‐porous channel reveals that nanoparticle shape, volume fraction, and magnetic effects significantly influence velocity and heat transfer. Results highlight strong coupling between geometric, electromagnetic, and thermophysical parameters in optimizing thermal system performance ...

Diffusion Processes in the A-Model of Vector Admixture: Turbulent Prandtl Number

EPJ Web of Conferences, 2018
Using analytical approach of the field theoretic renormalization-group technique in two-loop approximation we model a fully developed turbulent system with vector characteristics driven by stochastic Navier-Stokes equation. The behaviour of the turbulent
