Pressure‐driven flow in thin straight tubes of non‐uniform cross‐section

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 105, Issue 8, August 2025.
Abstract We analyze stationary Stokes flow of a Navier–Stokes fluid in a thin tube with a variable cross‐section. The objective is to derive a simplified model by examining the asymptotic behavior as the tube's thickness approaches zero. The flow is driven by a pressure gradient between the inlet and outlet, which is modeled by prescribing the normal ...

Propagation of weakly nonlinear axial waves of nanorods embedded in a viscoelastic medium

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 105, Issue 6, June 2025.
Abstract Nonlinear equations play a fundamental role in explaining complex systems in science and technology, particularly in the field of wave propagation. Nonlocal elasticity theory is a general method for analyzing nanostructures at the nanoscale. The current work utilizes Eringen's nonlocal constitutive equations to solve the nonlinear equations of

CONTROL OF MHD MICROPOLAR FLUID FLOW

Facta Universitatis, Series: Automatic Control and Robotics, 2020
In this paper, the steady flow and heat transfer of an incompressible electrically conducting micropolar fluid through a parallel plate channel is investigated. The upper and lower plate have been kept at the two constant different temperatures and the plates are electrically insulated. The applied magnetic field is perpendicular to the flow, while the

Magnetohydrodynamic Flow of Immiscible Couple Stress and Newtonian Fluids in a Porous Pipe With Navier Slip Effect

Heat Transfer, Volume 54, Issue 3, Page 1819-1831, May 2025.
ABSTRACT This work deals with the magnetohydrodnamic (MHD) flow of non‐miscible couple stress and Newtonian fluids within a horizontally‐oriented porous cylinder. The overall flow domain is divided into two separate regions. In the core area, identified as region I, the flow of the couple stress fluid takes place, while in region II, which forms the ...

The micropolar Navier-Stokes equations: A priori error analysis [PDF]

, 2013
The unsteady Micropolar Navier-Stokes Equations (MNSE) are a system of parabolic partial differential equations coupling linear velocity and pressure with angular velocity: material particles have both translational and rotational degrees of freedom.

Multiphysics Simulation Methods in Computer Graphics

Computer Graphics Forum, Volume 44, Issue 2, May 2025.
Abstract Physics simulation is a cornerstone of many computer graphics applications, ranging from video games and virtual reality to visual effects and computational design. The number of techniques for physically‐based modeling and animation has thus skyrocketed over the past few decades, facilitating the simulation of a wide variety of materials and ...

Influence of Joule Heating and Nonlinear Thermal Radiation on the Electrical Conductivity of Second‐Grade Hybrid Nanofluid Flow Over a Stretching Cylinder

Engineering Reports, Volume 7, Issue 4, April 2025.
The present study investigates heat and mass transfer of electrically conducting second‐grade hybrid nanofluid flow over a stretching cylinder in the presence of nonuniform heat sources and nonlinear thermal radiation. The application of such hybrid nanofluid in second‐grade fluid flow can significantly enhance thermal conductivity and heat transfer ...
