摘要

This study explores the flow behavior of a magnetized three-dimensional rotating penta-hybrid nanofluid (PHNF) over a stretched sheet, focusing on its potential applications in polymer processing and industrial cooling. The aim of the study is to investigate how various factors, such as nonlinear thermal radiation, heat source/sink, magnetic impact, porosity effects, and temperature ratio, influence the flow and heat transfer characteristics of PHNF. The modeling assumptions include the consideration of a porous medium, the influence of rotational effects, and the impact of magnetic fields on the fluid. The research methodology involves transforming the governing partial differential equations into ordinary differential equations using similarity transformations, followed by numerical solutions in MATLAB. The results show that higher radiation parameters and temperature ratios enhance fluid temperature, while magnetic fields and porosity reduce fluid velocity and boundary layer thickness. Additionally, the study finds that using PHNF instead of ternary hybrid nanofluid (THNF) leads to a reduction in the skin friction coefficient and an increase in the Nusselt number, making PHNF a superior candidate for heat and mass transfer applications in industrial systems. The findings highlight the practical value of PHNF in improving cooling efficiency and product quality, particularly in polymer processing applications such as blown film extrusion.
