Heat transfer analysis of nanofluid through inclined channels under the influence of thermal radiation and magnetic field

Abstract

This study explores Jeffery–Hamel (JH) flow using nanofluids, which have many practical applications in areas that need efficient heat transfer and precise control of fluid flow, especially in converging or diverging channels. These applications include technologies like heat exchangers, cooling systems for electronics, and solar thermal collectors. Specific applications include microscale heat sinks in electronic cooling, magnetohydrodynamic pumps in biomedical devices, and solar thermal collectors. Inspired by these real-world applications of Jeffery–Hamel flow, it is aimed to improve the thermal efficiency of the fluid, by introducing magnetic parameter and thermal radiation in the nanofluids. The analysis of this research study considers water based nanofluid with copper (Cu) as nanoparticles, which modeled a system of nonlinear equation and computed through NDSolve technique. The numerical results so obtained are compared with already existing studies, showing a good match and confirming the consistency of the proposed method. The study carefully examines, impact of the Hartmann number, nanoparticles concentration, and thermal radiation affects the velocity and temperature fields.
