Impact of Darcy–Forchheimer Inertial Drag and Heat Dissipation on Micropolar Hybrid Nanofluid Flow via Expanding Surface

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The hybrid nanofluid integrated with micropolar fluid shows growing interest due to the enhanced thermal performance in microscale devices. These improved properties are due to their greater thermal conductivity and rotational effects. The proposed study assesses the significance of velocity slip on the flow characteristic of micropolar ...

Anticlastic Curvature and Material Freedom

physica status solidi (b), EarlyView.
Anticlastic curvature occurs in bent bars for positive Poisson's ratio; synclastic curvature occurs for negative Poisson's ratio provided the material is homogeneous and elastic. Some planar negative Poisson's ratio materials exhibit anticlastic saddle curvature rather than convex curvature in bending due to effects of 3D structure.

Micropolar fluid flow through a stenosed bifurcated artery

Nonlinear Analysis, 2017
The aim of this article is to investigate the blood flow in bifurcated artery with mild stenosis taking blood as a micropolar fluid. The arteries, forming bifurcation are taken to be symmetric and straight cylinders of finite length.

Investigation of nanomaterials in flow of non-Newtonian liquid toward a stretchable surface

Open Physics, 2023
This article features the buoyancy-driven electro-magnetohydrodynamic micropolar nanomaterial flow subjected to motile microorganisms. The flow is engendered via an elongating surface, and the energy relation includes heat source generation ...

A control volume-based finite element method for plane micropolar elasticity [PDF]

, 2008
This paper describes the development of a numerical procedure for predicting deformations and stresses in a loaded two-dimensional membrane exhibiting micropolar or Cosserat constitutive behaviour. The procedure employs a conventional finite element (FE)

Cubic Lattice Rib Shape: Tuning of Poisson's Ratio and Cosserat Characteristic Length

physica status solidi (b), EarlyView.
Cubic rib lattices are studied in the context of effects of rib cross‐section shape on Poisson's ratio and on Cosserat characteristic length. It is possible to control Poisson's ratio over a wide range via appropriate rib cross‐section shape. Both Cosserat characteristic lengths can be made much larger than the cell size for torsion dominated rib ...

The effect of the hexachiral auxetic core on the thermomechanical vibration buckling analysis of smart sandwich nanoplates

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 105, Issue 6, June 2025.
Abstract This research examines the thermomechanical buckling characteristics of a smart sandwich nanoplate with a hexachiral auxetic core and electro‐elastic surfaces, employing non‐local strain gradient elasticity and higher‐order shear deformation theory.

Elastic‐Wave Propagation in Chiral Metamaterials: A Couple‐Stress Theory Perspective

Advanced Engineering Materials, Volume 27, Issue 9, May 2025.
The intrinsic chirality of chiral metamaterials renders an effective medium based on the classical continuum theory ineffective for predicting their acoustic activity. This limitation is addressed in the present study by employing augmented asymptotic homogenization to derive a couple‐stress‐based effective medium, enabling accurate predictions in the ...
