Lagrangian Statistics of Heat Transfer in Homogeneous Turbulence Driven by Boussinesq Convection
Fluids, 2020 The movement of heat in a convecting system is typically described by the nondimensional Nusselt number, which involves an average over both space and time.

High-Reynolds number calculations of turbulent heat transfer in FlowVision software [PDF]
Компьютерные исследования и моделирование, 2018 This work presents the model of heat wall functions FlowVision (WFFV), which allows simulation of nonisothermal flows of fluid and gas near solid surfaces on relatively coarse grids with use of turbulence models.

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.

MODELING HEAT EXCHANGE DEPENDING ON THE PRANDTL NUMBER FOR VARIOUS GEOMETRIC AND REGIME PARAMETERS
Вестник Дагестанского государственного технического университета: Технические науки, 2020 Objectives. The aim is to study the dependency of the distribution of integral heat transfer during turbulent convective heat transfer in a pipe with a sequence of periodic protrusions of semicircular geometry on the Prandtl number using the calculation ...

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

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 ...

Effect of Tunnel Ventilation on Hydrogen Dispersion From Leaks in Hydrogen Fuel Cell Trucks
Energy Science &Engineering, Volume 14, Issue 8, Page 3608-3624, August 2026.This study investigates hydrogen leakage scenarios involving hydrogen fuel cell trucks within tunnels. Using computational fluid dynamics methods, it explores the distribution characteristics of hydrogen concentrations and the efficiency of ventilation under different forced ventilation conditions. ABSTRACT The widespread adoption of hydrogen fuel cell

Lubrication Science, Volume 38, Issue 5, Page 301-326, August 2026.ABSTRACT Porous gas bearings (PGBs) enable high‐speed, oil‐free operation in modern rotating machinery. This study develops a coupled thermo‐hydrodynamic (THD) model for a cylindrical porous gas bearing lubricated with four working fluids—air, R‐134a, helium and hydrogen.
