This article investigates the pressure-driven flow of a magnetized hybrid nanofluid confined between two curved corrugated walls in presence slip constraints. The base fluid, water, is augmented with single-walled and multiwalled carbon nanotubes (SWCNTs MWCNTs) to enhance thermal conductivity, evaluated using Xue Yamada–Ota models. channel geometry mathematically modeled an orthogonal curvilinear coordinate system, sinusoidal functions describing corrugation grooves phase differences walls. An analytical solution for velocity temperature profiles derived boundary perturbation method, amplitude as parameter. effects various physical parameters on fields are thoroughly analyzed presented graphs tables. Additionally, key quantities such volumetric rate, skin friction coefficient, local Nusselt numbers numerically computed different parameter values comprehensively tabulated. results reveal significant reduction profile increasing curvature Comparisons indicate that model outperforms terms predictive capability robustness. Finally, trapping process examined detail through construction contour streamlines.

Dynamics of accelerating and decelerating flow of an electrically conducting Jeffrey fluid between two narrowly flat permeable disks

Advances in Mechanical Engineering, Journal Year: 2025, Volume and Issue: 17(4)

Published: April 1, 2025

The radial flow between two flat disks plays a crucial role in engineering and industrial applications due to its relevance lubrication systems, cooling technologies, fluid transport mechanisms. This study investigates the laminar of an incompressible Jeffrey permeable under influence magnetic field. exact solutions for both accelerating decelerating flows are derived using Jacobi elliptic function first kind. effects key physical parameters on velocity profiles analyzed graphically, while torque variations presented tabular form. Additionally, streamline patterns 2D graphs exhibit consistent trends across parameter variations, reinforcing accuracy findings. Results indicate that increases with stronger field but decreases all other parameters. In contrast, rises increasing porosity declines remaining factors. Torque analysis reveals increase enhances disks, whereas higher Darcy number upper disk reduces it lower disk. Streamline is conducted illustrate behavior varying conditions. results confirm parabolic profile, maximum at central region minimum surfaces.
