Asymptotic analysis for micropolar fluids

Comptes Rendus. Mécanique, 2003
The flow of a micropolar fluid through a wavy constricted channel which depends on a small parameter ε⪡1 is considered. The asymptotic solution is built and justified thanks to a study of the boundary layers terms. The Stokes and Navier–Stokes problems set in a tube structure were previously considered. The method of partial asymptotic decomposition of

Flow of Elastoviscous Nanofluid Through an Elongating Surface With Dissipative Heat: A Confluent Hypergeometric Solution

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 1, January/February 2026.
ABSTRACT Thermal energy transport likely through polymer extrusion, cooling of metallic plates, and chemical processing equipment relating to the flow of viscoelastic nanofluid has a greater role in engineering because of its elastic characteristics.

Unsteady unidirectional micropolar fluid flow

Theoretical and Applied Mechanics Letters, 2011
AbstractThis paper considers the unsteady unidirectional flow of a micropolar fluid, produced by the sudden application of an arbitrary time dependent pressure gradient, between two parallel plates. The no-slip and the no-spin boundary conditions are used. Exact solutions for the velocity and microrotation distributions are obtained based on the use of

When Scale Matters: Size‐Dependent Mechanics of Architected Lattices for Implants and Beyond

Small Structures, Volume 7, Issue 1, January 2026.
Mechanical metamaterials exhibit size‐dependent behaviors that challenge conventional design assumptions. This study systematically explores how unit cell dimensions influence elastic properties under compression, shear, and torsion. Finite element simulations and experiments reveal critical size parameters shaping mechanical performance, offering new ...

Energy Transport Analysis of Bioconvective Magnetized Micropolar Fluid Flow Over a Porous Curved Stretching Surface With Homogeneous–Heterogeneous Reactions

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Efficient energy transport in complex fluids is essential for the optimal design of modern thermal and bio‐energy systems. In this study, the bioconvective flow and heat transfer characteristics of a two‐dimensional, incompressible magnetized micropolar fluid of second‐grade nature over a porous curved stretching surface are investigated.
