Abstract
Abstract The principal focal point of the current review is the second-grade nanofluid (SGNF) stream with slanted magnetohydrodynamics and viscous disintegration impacts across a moving level flat surface with entropy investigation. Here, we have done a comparative study on copper–methanol and iron–methanol second-grade nanoliquids. The governing conditions of the SGNF model are changed into ordinary differential equations (ODEs) by using supportive changes. To tackle the non-straight ODEs, the Runge-Kutta Fehlberg-45 procedure is utilized. The result reveals that the velocity gradient of copper–methanol second-grade nanoliquid is strongly affected by suction, magnetic, and second-grade fluid parameters and declines faster when compared to iron–methanol second-grade nanoliquid. Copper–methanol SGNF shows improved heat transfer than iron–methanol SGNF for improved values of Eckert and Biot numbers.
