Enhancing Efficiency in Double‐Pipe Heat Exchangers: A Detailed Review of NanoFluids and Their Impact on Thermal Performance

open access: yesHeat Transfer, Volume 55, Issue 1, Page 212-240, January 2026.
ABSTRACT This study reviews recent advances in using nanofluids to enhance double‐pipe heat exchanger (DPHE) efficiency. The review examines several types of nanofluids, that is, water‐based graphene oxide and CuO–water nanofluids, assessing their effectiveness under different operating conditions, including inlet temperature and nanoparticle volume ...

Scaling and spatial intermittency of thermal dissipation in turbulent convection

open access: yes, 2019
We derive scaling relations for the thermal dissipation rate in the bulk and in the boundary layers for moderate and large Prandtl number (Pr) convection.

Exploring the Effects of Reduced Gravitational Field Impacts on Convective Heat Transfer: A Comprehensive Review

open access: yesHeat Transfer, Volume 55, Issue 1, Page 764-774, January 2026.
ABSTRACT This review explores the impact of gravitational instability on convective heat transfer, integrating existing research results and theoretical models. Gravitational instability is vital in promoting or hindering convective actions in different systems, such as atmospheric events, ocean currents, and industrial processes.

Flow Regulation in a T‐Shaped Mixing Channel Using a Proportional‐Integral‐Derivative Controller

open access: yesThe Journal of Engineering, Volume 2026, Issue 1, January/December 2026.
This study investigates mixed convection in a 2D T‐shaped channel with a heated cylinder, employing a PID controller to regulate airflow and maintain consistent outlet temperatures. Using the Galerkin finite element method (GFEM), the effects of varying PID parameters on system stability and response time are analysed.

A unified thermo‐chemo‐mechanical model for passive, active, and interfacial oxidation of silicon carbide

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract Silicon carbide (SiC) is a promising material for hypersonic thermal protection systems, but its complex oxidation behavior—marked by transitions between passive, active, and interfacial bubbling regimes—can lead to catastrophic failure. Existing SiC models typically focus exclusively on either passive or active oxidation.

Heat Transfer of Viscous MHD Nanofluid Flow in the Presence of Solar Radiation With Entropy

open access: yesAbstract and Applied Analysis, Volume 2026, Issue 1, 2026.
To satisfy the power needs of human beings without affecting the environment, scientists have been working on the efficient practices of renewable energy sources such as solar, water, and wind. As a source of energy resources, solar radiation is preferred because of its unlimited availability and low ecological impact.
