The primary objective of the work is to elucidate the impact of inclined viscous dissipative magnetisation and ohmic heating on the steady-state flow of Casson nanofluid across a stretched sheet inside a porous medium including a heat source or sink. In this study, we consider convective heating in relation to temperature and particle slip conditions to determine velocity and concentration. The thermal radiation and Soret effects with chemical reaction are also considered. The energy and concentration equations incorporate Brownian motion and thermophoretic phenomena to accurately depict the behaviour of nanofluids within the boundary layer domain. We have used a typical Casson fluid model to differentiate the flow properties of non-Newtonian fluids from Newtonian fluids. We construct a coupled, nonlinear system of partial differential equations to describe the behaviour of heat and mass transfers. Similarity transformations are employed in sequence to lower the dimensional difficulty of the resulting differential equations. Here we use the bvp4c Matlab solver to find out the solutions for velocity, temperature, and concentration. The main outcome of this study is that the velocity of the Casson nanofluid reduces significantly whilst the thermal field rises as the inclined magnetisation increases. Additionally, increasing Eckert number result in increased thermal transport. An increase in the slip effect leads to a reduction in both concentration and velocity distribution. On the other hand, a higher value of porosity reduces velocity distribution. Finally, we verify the generated bvp4c solutions by comparing them to the existing solutions, finding remarkable agreement.
