Abstract: The heat transfer problem over an inclined surface has emerged as a significant topic of interest among researchers. Its application has grown and has been highlighted particularly because of its durability in engineering developments. Hence, in accordance with the current phase of development, a mathematical model of steady flow and heat transmission involving an alumina-copper dusty hybrid nanofluid across inclined, stretched, and shrunk surfaces by implementing viscous dissipation and slip conditions has been proposed. Similarity transformations were utilized in reducing the governing equations to a set of ordinary differential equations (ODEs), and the numerical results were achieved by employing a bvp4c solver in MATLAB. The findings highlighted that dual solutions occur in both cases for shrinking surfaces. Moreover, both the skin friction coefficient and the rate of heat transmission decrease with increasing inclination angle. In contrast, the rise in Eckert number values, which implies viscous dissipation, depicts an upsurging pattern for the coefficient of skin friction while diminishing the rate of heat transmission between the fluid flow and the surface.
