Abstract
Practical Applications: Numerous technical applications, including as polymer deposition, electrolysis control, medication delivery, spin-stabilized missile cooling and cooling of rotating machinery slices have sparked considerable interest in studying stagnation point flow. Nuclear power plants, photovoltaic panels and heat exchangers as well as microfluidic heating devices use them.
Purpose: To better understand the unsteady (Cu-Fe3O4-SiO2/polymer) ternary hybrid nanofluid stream at the stagnation zone with Joule heating, this research examines the unique prospective applicative properties.
Methodology: The flow equations will be modeled. By using similarity transformation, it is possible to transform nonlinear partial differential equations (PDEs) that are not precisely solvable into ordinary differential equations (ODEs) that can be numerically resolved. Runge-Kutta-IV and the shooting technique in MATHEMATICA have been demonstrated to have a significant effect on the predominance of heat exchange and the mobility features of ternary hybrid nanofluids.
Findings: Results show that the unsteadiness parameter influences the x-direction velocity and mono nanofluid has a larger velocity than other nanofluids, while the opposite is true for the z-direction velocity. Nanoparticle concentrations, magnetic and Eckert number characteristics increase the thermal distribution, whereas the unsteadiness and rotation parameter decreases it. Unsteadiness, rotation and magnetic factors all improve heat transfer, while the Eckert number parameter has the reverse effect. The ternary hybrid nanofluid also has a greater heat transfer rate than the hybrid and normal nanofluids.
Originality: Unsteady (Cu-Fe3O4-SiO2/polymer) ternary nanofluid stream generated by magneto hydrodynamic (MHD) in the stagnation zone was studied in detail in this study. To avoid any errors in heat transfer, it may assist other researchers in selecting critical parameters for modern industrial heat transfer and the right parameters for developing nonunique solutions.
