Particle Size Effects on Dynamic Behavior of Heated Spheroidal Particles in Shear Flow

Chemical Engineering &Technology, Volume 49, Issue 3, March 2026.
Understanding the dynamics of nonspherical particles in shear‐driven flows is essential for a wide range of engineering applications. This study examines how confinement ratio, thermal effects, and interparticle interactions influence the migration, equilibrium positions, and rotation of nonspherical particles in such flows.

Statistical and Numerical Analysis of Conjugate Heat and Momentum Transfer in an Open Cavity With a Thick Wall Using Cu–Water Nanofluid

Engineering Reports, Volume 8, Issue 3, March 2026.
Considered physical model and effect of Nuav(τ = 0.1) for Re and ϕ at τ = 0.1. ABSTRACT Although open cavity configurations are common in modern electronic and solar applications, limited attention has been given to thick‐walled hollow cavity designs, particularly in the context of comprehensive sensitivity analysis.

Finite Element Analysis and ANN Validation of Mixed Convection Nanofluid Flow in a Star‐Shaped Corrugated Cavity With Multiple Heated Baffles

Engineering Reports, Volume 8, Issue 3, March 2026.
This study carefully examines the mixed convection heat transport properties of a water–Al2O3 nanofluid inside a corrugated chamber with heated baffles in the shape of a star. The effects of different Rayleigh numbers, nanoparticle volume fractions, and baffle placement are carefully evaluated, and the cavity is subjected to buoyancy forces. The finite

Remobilisation of fine sediment from chalk stream gravel beds under flushing flows: A flume experiment

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Through progressive flume experiments, this study demonstrated that increased bed shear stresses corresponded with increased cohesive fine sediment (<62‐μm) remobilisation depths from a representative chalk stream gravel bed. This represents some of the first scientifically robust data, which can direct revised and targeted fine sediment management in ...

On the Onsetof Thermal Instability in a Low Prandtl Number Nanofluid Layer in a Porous Medium

Journal of Applied Fluid Mechanics, 2015
Thermal instability in a low Prandtl number nanofluid in a porous medium is investigated by using Galerkin weighted residuals method for free-free boundaries. For porous medium, Brinkman-Darcy modelis applied.

A Phenomenological Interpretation of Laminar Natural Convection Correlations

Applied Sciences
Natural convection heat transfer is commonly described using dimensionless correlations relating the Nusselt number to the Grashof and Prandtl numbers. For gases and non-metallic liquids, these parameters combine into the Rayleigh number, Ra=Gr·Pr, while

Entropy Generation Analysis due to Permeable Exponential Stretching in Boundary Layer Flows

Heat Transfer, Volume 55, Issue 2, Page 781-796, March 2026.
ABSTRACT Entropy generation represents the irreversible loss of useful energy in thermal–fluid systems, directly reducing efficiency in applications, such as microelectronics cooling, nanofluid‐based heat exchangers, and polymer processing. This study investigates entropy generation in a two‐phase viscoelastic nanofluid flow over a permeable ...
