Industrial applications in domains such as warm rolling, crystal development, thermal extrusion and optical fiber illustration are seeing a significant increase. These specifically focus on addressing the challenge of cylinder motion inside fluid environment. Elevated temperatures may affect viscosity conductivity fluids. Understanding relationship between temperature properties fluids is crucial. In light these presumptions, primary goal this study to examine, under transverse magnetic field, shape factor, velocity, slip conditions viscous dissipation, how temperature-dependent could enhance heat transfer efficiency performance evolution ternary hybrid nanofluid. order flow fluctuations, impact nanoparticle addition improvements transfer, variable Prandtl number also included. The use similarity variables converts controlling model from partial differential equations (PDEs) ordinary (ODEs). Mathematica’s shooting strategy solves ODEs using fourth-order Runge–Kutta (RK-IV) method. Numerical calculations were done after setting parameters acquire desired results. Analytical data provided tables graphs for convenient usage. results showed that velocity profile increases values [Formula: see text], Pr, M, Re S grow, decreases when text] decrease.

Nanofluids have captured the attention of scientists due to their superior thermophysical properties compared ordinary liquids. Consequently, nanofluids serve as suitable cooling agents applicable systems requiring swift response thermal changes, such vehicle engines. Therefore, current article scrutinizes characteristics heat transfer on pressure-driven flow magnetized nanofluid between two curved corrugated surfaces in presence generation/absorption.

The geometry channel is represented mathematically an orthogonal curvilinear coordinate system. corrugation grooves are described by sinusoidal functions phase differences walls. boundary perturbation method used find analytical solution for velocity field, temperature and volumetric rate taking amplitude parameter. impact dissimilar parameters curvature parameter (0.5≤k≤10), wave number (1≤α≤3), magnetic (1≤M≤5), (0.1≤ε≤0.8) fields analyzed through graphs discussed detail. results show that peak increases radius width constant pressure gradient. If we increase from 1 4, profile at specified point decreases 30 %. source/sink 2 5, approximately 17 increased corrugations any difference walls depending wavenumber curvature.

Published: March 29, 2025

Numerically, the effect of melting heat transfer on magnetohydrodynamics (MHD) tangent hyperbolic nanofluid (Thnf) flow across a porous wedge is evaluated. Electronic devices generate lot while running, so Thnf commonly used to reduce its temperature. has ability more effectively, thus minimizing risk high temperature and component disruptions. The impact source/sink, thermal radiation, homogeneous/heterogeneous chemical reactions also observed in fluid flow. modeled equations are reformulated into non-dimensional form ordinary differential (ODEs), which further numerically solved through nonlinear dynamics (ND)-solve approach. For validity results, numerical outcomes relatively related published studies, reveal that proposed model results accurate consistent. Furthermore, it can be determined from graphical velocity drops with rising permeability parameter whereas enhances positive variation power law index. increasing influence angle parameters augments energy distribution rate. intensifying heterogeneous homogeneous reaction decreases concentration profile.
