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

Computational Analysis of Prandtl on the Fluid Relaxation Time Features for the Energy and Concentration Nanomaterial Flow of Motile Microorganisms Induced by a Deformable Sheet With Chemical Reactions

International Journal of Differential Equations, Volume 2026, Issue 1, 2026.
This study investigates the phenomenon of bioconvection in a Darcy–Forchheimer flow of a Prandtl fluid on a stretching sheet, considering dual diffusive processes and incorporating the Cattaneo–Christov heat conduction model. For the conversion of modeled equations to dimensionless, a suitable set of variables has been incorporated.

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

Eco‐Smart Ionic Liquids in the 21st Century: A Comprehensive Review on Molecular Innovation for Sustainable Environmental Solutions

Journal of Engineering, Volume 2026, Issue 1, 2026.
Ionic liquids (ILs) have matured from laboratory curiosities to eco‐smart, molecularly tunable media underpinning sustainable chemical technologies. This review integrates a bibliometric mapping of the 2000–2025 literature with a critical synthesis of IL design principles, structure–property relationships, and application landscapes.

Full‐Length FUS Protein Condensates Adopt a Domain‐Preferential Spatial Architecture

Aggregate, Volume 6, Issue 12, December 2025.
We demonstrate a domain‐specific preferential distribution organization of FUS condensate and propose a sequence–structure–function paradigm for biomolecular condensates. ABSTRACT Biomolecular condensates play crucial roles in cellular physiology and are implicated in neurodegenerative diseases and cancer.

A New Pressure Regularity Criterion of the Three-Dimensional Micropolar Fluid Equations

Journal of Applied Mathematics, 2013
This paper concerns the regularity criterion of the weak solutions to the three-dimensional (3D) micropolar fluid equations in terms of the pressure. It is proved that if one of the partial derivatives of pressure satisfies ∂3π∈Lp(0,T;Lq(R3)) with 2/p+3 ...
