Abstract

This paper investigates how higher-order velocity slip affects the flow of Casson nanofluid over a stretched sheet within the boundary layer (BL), considering an inclined magnetic field and the Buongiorno model. The similarity transformation is used to convert a collection of ordinary differential equations into a collection of partial differential equations. The Spectral Quasi-linearization approach is used to solve the modeled system numerically and examine how various fluid parameters affect the temperature, concentration, and velocity profiles. The findings of the important physical characteristics have been depicted graphically. It is observed that velocity reduces but temperature enhances for an increment of magnetic field parameter, inclination angle, Casson parameter, and first-order velocity slip parameter. Also, concentration increases close to the sheet but declines far from the sheet for larger values of Brownian motion parameter and Schmidt number. From an MHD flow and heat transfer perspective, numerous engineering applications can benefit, including petroleum processing, MHD power generation, aerodynamic boundary layer control, polymer sheet production, glass fiber manufacturing, and many others.
