Abstract
Abstract The remarkable characteristics of CNTs, comprising their powerful tensile strength, superb thermal electrical conductivities, and chemical and mechanical flexibility, render them highly appealing for electrochemical gadgets. This research focuses on these outstanding qualities by numerically analyzing the steady 3D slanted magnetic effects on mass and heat transmission in the flow of a Casson hybrid nanofluid across a permeable stretchable surface. The hybrid nanofluid comprises the SWCNTs and MWCNTs distributed in water as the base fluid. Critical elements like the rotational parameter, heat generation/absorption, magnetic inclination angle, heat radiation, and homogeneous–heterogeneous reactions are considered while analyzing heat transfer caused by a spinning stretched sheet. Utilizing appropriate similarity variables, the set of partial differential equations that make up the physical flow model is converted into associated nonlinear ordinary differential equations. The bvp4c method is employed to tackle the modified non-dimensional boundary value problem (BVP). According to the graphical data, the temperature profile is improved by raising the Biot number and the heat source parameter, strengthening the thermal boundary layer. The behavior of essential flow components is depicted in tables and graphs, and the results are confirmed by comparison with previous research, which reveals a high degree of agreement. The Nusselt number and friction drag are also analyzed to understand the fluid flow behavior. This study’s results can potentially improve the performance of thermal engineering systems and devices across various industrial and thermal applications.
