Comparative study of oblique stagnation point flow of MWCNT-Ag/blood and MWCNT/blood nanofluids due to shrinking surface

Abstract

Hybrid nanofluids improved the thermal characteristics and stability features of various applications including thermal efficiency systems, solar collectors, energy production, nuclear processes, and heat transfer properties. Motivated by above mentioned applications of hybrid nanofluids, the primary aim is to explore the heat transfer analysis through a comparative study of (MWCNT-Ag/blood) hybrid nanofluid and (MWCNT /blood) nanofluid near an oblique stagnation point flow with the impact of non-linear thermal radiation, variable thermal conductivity and non-uniform heat generation/absorption across a shrinking surface. The influence of suction, convective boundary condition are also under consideration. The governing flow problem is reformed into non-linear ODEs employing appropriate similarity variables. A suitable technique bvp4c built-in MATLAB function used for numerical solutions. A comprehensive analysis of distinct influential fluid factors against drag friction, Nusselt number, flow, and thermal transportation are examined graphically. The outcome shows that friction drag increases with the increment in suction parameter for both hybrid and monofluids for stable branch solutions. Furthermore, heat transportation rate rises with the addition of variable thermal conductivity and radiation factors for hybrid nanofluid and monofluid. It also observed that hybrid nanofluid boosted rapidly compared to a naonofluid, representing an improvement in thermal characteristics is more stable for hybrid nanofluid than monofluid. Additionally, increasing the temperature ratio factors shows an upsurge in thermal distribution profile.
