Abstract The Joule heating effect plays a crucial role in numerous electrical and electronic applications, including electron microscopes, flash pasteurization systems, electric power generation, cartridge warmers, various other devices. This article aims to delve into the of steady 2‐D stagnation point flow hybrid nanofluid (HNF) (MWCNT+Fe 3 O 4 /H 2 O) towards stretching surface with magnetic effects. In addition, heat source, viscous dissipation, varying thermal conductivity, velocity slip, radiation are also considered while analyzing characteristics. governing partial differential equation (PDE) equations have been converted via similar variables set ordinary (ODEs). These numerically solved using fourth‐order Runge–Kutta method shooting technique. effects different physical parameters on velocity, temperature, Nusselt number, drag force coefficient graphically analyzed. results demonstrate that an increase parameter (Rd) (M) enhances transfer rate at surface. Moreover, associated Eckert number indicates HNFs achieves 3.94% improvement compared mono‐nanofluids 2.28% fluids.

In this investigation, local thermal non-equilibrium, elastic deformation impact on MHD Williamson hybrid nanofluid across a sheet utilizing permeable media, and viscous dissipation features are examined. The of chemical reaction Cattaneo-Christov heat flux taken into consideration in the modeling. Mass transfer phenomena were modified from general theory, which considers importance relaxation times. non-equilibrium model is based energy equations provides efficient transmission for both liquid solid phases. Therefore, two distributions used fluid specific piece work. ( SiC -- Co 3 O 4 NAC 6 H 7 ) flow contains nanoparticles diamond ND ), Cobalt oxide (Co silicon carbide dissolved Sodium alginate (NAC ). It essential design sophisticated cooling systems that require precise temperature management, as those found microelectronics aircraft. can also be applied biomedical engineering to medication delivery nanofluids. Furthermore, its application materials science improve characteristics nanocomposites manufacturing processes, leading more effective better control. equation system theoretically solved using Bvp4c method once pertinent similarity variables have been reduced. To illustrate how different physical conditions, affect involved distributions, findings graphed. When interphase parameter increased, phase’s transport rate rises although decreases.
