The objective of the proposed study is to investigate the magnetohydrodynamic flow characteristics of a Casson nanofluid transport on a nonlinear oblique extending absorbent surface, considering the role of heat generation and Ohmic heating. The incorporation of Ohmic heating in a viscoplastic nanofluid plays a crucial role in enhancing the uniqueness of this work. This Ohmic heating significantly affects heat transport properties and nanofluid flow behavior in more effective energy transfer frameworks. Also, the Buongiorno model is a widely used and precise technique for the modeling of fluid flow problems utilized in solar systems. Similarity conversions are utilized to minimize the leading equations into a set of coupled ordinary differential equations (ODEs) from controlling partial differential equations. These coupled ODEs governing the momentum, heat, and mass are numerically solved. The Runge–Kutta fourth order method combined with the shooting technique for the non-dimensional governing ODEs is employed to analyze the features of key aspects incorporated in the flow regime. A comprehensive scrutiny of controlling parameters is carried out, and numerical outcomes are depicted as graphical illustrations and in tabular format. In addition to this, the practical applications of engineering quantities on the Nusselt number are visualized and discussed via statistical analysis. The obtained outcomes are compared with results that have already been published, and a good match is found. The improvement of the Hartmann number, mass Grashof number (Gr), Casson parameter, and inclination angle reduces the fluid velocity, while increasing the thermal Gr exhibits an opposite behavior. Augmenting the thermal radiation parameter, Eckert number, thermophoresis, and Brownian motion parameter (Nb) enhances the fluid temperature distribution. The fluid temperature rises upon accelerating the thermophoresis parameter, while the contrary result is obtained upon improving the Lewis number and Nb. The drag friction coefficient is improved by enhancing the thermal Gr and Casson parameter.
