Thermal and flow transfer characteristic of two-phase dusty viscoelastic Maxwell hybrid nanofluid over a porous radiative cylinder

Abstract

This study undertakes a numerical investigation into the two-phase magnetohydrodynamic (MHD) flow of a novel Al2O3-Ag/ethylene glycol (30%)–water dusty Maxwell hybrid nanofluid within a porous stretched cylinder incorporates the influential factor of thermal radiation. Notably, it pioneers exploration into the flow characteristics of Maxwell nanofluids and hybrid nanofluids containing dust particles over a porous cylinder, an uncharted domain in the existing literature. By adeptly simplifying the governing partial differential equations into nonlinear ordinary differential equations (ODEs) using judiciously chosen similarity variables, our research employs MATLAB’s bvp4c scheme to obtain numerical solutions, presented both graphically and in tabular form. Our results unveil significant insights: the Maxwell fluid parameter and magnetic parameter exhibit a dual effect of enhancing heat transfer while mitigating velocity gradients. Moreover, increasing the curvature parameter exerts a favorable influence on the velocity and temperature profiles of both phases. Furthermore, the fluid-particle interaction parameter emerges as a pivotal factor shaping velocity and temperature profiles in the dust phase, while the radiation parameter notably amplifies heat transfer rates. Remarkably, our investigation reveals a notable 26% increase in total skin friction and a nearly 13.5% enhancement in heat transfer within the dusty Maxwell hybrid nanofluid configuration compared to the dusty Maxwell nanofluid arrangement. These findings hold profound practical implications for addressing real-life engineering challenges, offering invaluable insights into optimizing heat transfer and velocity profiles across diverse technical applications. They pave the way for the development of enhanced cooling mechanisms and highly efficient heat exchangers, crucial for tackling multifaceted engineering challenges.
