Impact of linear/nonlinear radiation on incessantly moving thin needle in MHD quiescent Al-Cu/methanol hybrid nanofluid

Abstract

ABSTRACT The present work describes the periphery layer exploration of a magnetohydrodynamic hybrid nanofluid (Al-Cu/methanol) flow besides an unceasingly moving needle submerged horizontally in the flow field. The presumption is that the thermal radiation is linear/nonlinear. The border layer conduct is inspected under the purview of Sakiadis (quiescent fluid) situation. The central system of partial differential equations’ is transmuted as a system of ordinary differential equations' and unravelled by engaging the R-K method established shooting technique. Numerical deduction of thermal transport, wall friction is tabulated and accordingly interpreted. The designations of velocity and thermal fields are examined by graphical illustrations. Simultaneous solutions attained to reveal the superior nature of aluminium-copper/methanol hybrid nanofluid compared to methanol-based Al-Cu alloy nanofluid (with 50% aluminium and 50% copper). An elevation in needle thickness has an increased implication on the heat transfer rate of hybrid nanoliquid. Also, nonlinear thermal radiation has remarkable influence on thermal profiles than linear.
