Magnetohydrodynamics Stagnation Point Flow of Hybrid Nanofluids with Distinct Base Fluid Over an Exponentially Extending Cylinder: A Numerical Comparative Analysis

Abstract

Thermal transmission is very significant in the industrial and engineering sectors. This research aims to investigate the MHD stagnation point movement of methanol and water-driven [Formula: see text] hybrid nanofluid flow via an exponentially extending cylinder. An inclined magnetic field’s control, suction or injection and viscous dissipation impacts are used and considered in the flow paradigm, as no prior research has been performed on it. This motivated the authors to perform a computational analysis of the distinct base fluid (water and methanol)-driven hybrid nanofluid flow with the aforementioned impacts, which gives distinctiveness to the flow model. The basic partial differential equation flow mechanism has been streamlined to nondimensional ordinary differential equations by the inclusion of distinct dimensionless factors, which are simulated employing the BVP4c methodology. The impacts of dimensionless variables, namely the Eckert factor, suction/injection term, Biot factor, velocity ratio term and magnetic factor, on the flow speed, thermal distribution, rate of shearing stress and thermal transmission are delineated in figures and demonstrated with tables. The major findings specify that methanol-based hybrid nanofluid ([Formula: see text]/methanol) has a significantly higher thermal transmission rate when compared with the water-based hybrid nanofluid ([Formula: see text]/water). Furthermore, it has been shown that the methanol-based hybrid nanofluid has an absolute friction drag that is up to 26.5% larger than that of nanofluid. The thermal gradient reduces with the enhancement of [Formula: see text] and [Formula: see text]. Moreover, the fluid temperature upsurges as [Formula: see text] and [Formula: see text] elevate. These outcomes significantly advance fluid dynamics and nanofluid research, offering opportunities for improved thermal transmission in numerous industrial and engineering sectors. A noteworthy validation with previously published work has also been performed.
