Arbitrary Lagrangian–Eulerian Formulation in a Rotating Frame to Model Friction Spinning

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Friction spinning is a metal forming process that can be used to manufacture various shapes by rotating a metallic workpiece relative to a blunt tool. When used as a hot metal forming process, the relative velocity between workpiece and tool is increased until substantial heat is generated due to friction.

Gradient‐Based Optimization Modeling of Total Entropy and Heat Transfer in Exothermic Blood Analog Gold Nanoparticle Suspension

Engineering Reports, Volume 8, Issue 9, September 2026.
This study develops a gradient‐based multi‐start Nelder–Mead optimization framework for Casson‐micropolar blood‐analog nanofluid flow with gold nanoparticles in a convectively heated, exothermic microchannel, motivated by photothermal drug delivery. Spectral collocation solves coupled momentum, microrotation, and energy equations, from which entropy ...

Thermal and Bioconvective Modeling and Analysis of Unsteady Cu‐Water Nanofluid Flow through Porous Media with Gyrotactic Microorganisms

Engineering Reports, Volume 8, Issue 9, September 2026.
The current study investigated unsteady boundary layer flow of a Cu/H2O$$ \mathrm{Cu}/{\mathrm{H}}_2\mathrm{O} $$ nanofluid over an expanding sheet embedded in a Darcy porous medium, containing gyrotactic microorganisms. The model includes heat source effects, unsteadiness, buoyancy, slip conditions, and nanoparticle radius.

A Review of Flow Field and Heat Transfer Characteristics of Jet Impingement From Special‐Shaped Holes

Engineering Reports, Volume 8, Issue 9, September 2026.
Special‐shaped nozzles and nanofluid integration enhance jet impingement cooling by improving heat transfer and thermal uniformity. However, gains are constrained by increased pressure drop and stability challenges, highlighting the need for optimized designs and multiscale modeling to achieve efficient, scalable thermal management.

A Hybrid FEM–ML Framework for Magnetohydrodynamic Combined Convective Heat Transfer Performance of Hybrid Nanofluid Flow in a Horizontal Wavy Channel

Engineering Reports, Volume 8, Issue 9, September 2026.
The maximum heat transfer rate is observed at Ri = 10, Ha = 0, and ϕ = 0.06 under the default parameter settings for different boundary conditions. The proposed ANN model demonstrates good predictive and classification accuracy in estimating the average Nusselt number for both cases. ABSTRACT This computational study introduces a novel hybrid framework

Thermal Behavior of Radiative Darcy–Forchheimer Nanofluid Flow With Heat Source/Sink Effects

Engineering Reports, Volume 8, Issue 9, September 2026.
Radiative Darcy–Forchheimer nanofluid flow in a porous medium is numerically analyzed with heat source/sink effects. Radiation enhances heat transfer and boundary layer thickness, while increasing Forchheimer resistance suppresses velocity, providing insights for optimizing thermal management in high‐temperature porous systems.
