Abstract
The key objective of the study under concern is to probe the impacts of Brownian motion and thermophoresis diffusion on Casson nanofluid boundary layer flow over a nonlinear inclined stretching sheet, with the effect of convective boundaries and thermal radiations. Nonlinear ordinary differential equations are obtained from governing nonlinear partial differential equations by using compatible similarity transformations. The quantities associated with engineering aspects, such as skin friction, Sherwood number, and heat exchange along with various impacts of material factors on the momentum, temperature, and concentration, are elucidated and clarified with diagrams. The numerical solution of the present study is obtained via the Keller-box technique and in limiting sense are reduced to the published results for accuracy purpose.

Brownian motion and thermophoresis diffusions are the key notions of abnormal improvement in thermal conductivity by using binary fluids
For the numerical results of physical parameters of our concern, namely, Brownian motion denoted by Nb, thermophoresis given by Nt, magnetic factor M, buoyancy factor λ, solutal buoyancy constraint δ, inclination factor γ, Prandtl number Pr, Lewis number Le, radiation factor N, Casson fluid parameter β, Biot number γ1 and parameter m, several figures and tables are prepared
By enhancing the Brownian motion impact, the thermal boundary layer thickness increases, and it effects a large amount of the fluid
Summary
Brownian motion and thermophoresis diffusions are the key notions of abnormal improvement in thermal conductivity by using binary fluids (base fluid along with nanoparticles). The impacts of Brownian motion and thermophoresis diffusion on Casson nanofluid flow on a stretching sheet were discussed by Anwar et al [1]. The radiation effects on Casson nanofluid flow on a nonlinear slanted sheet were investigated by Ghadikolaei et al [14]. Casson fluid flow on an inclined sheet with multiple impacts was discussed by Jain and Parmar [30]. The thermal radiation impact on flow and heat exchange is a key factor to design advanced energy conversion systems [42]. Ghadikolaei et al [43] investigated the flow of Casson nanofluid on a porous inclined sheet numerically. To the best of the authors’ knowledge, no study on Casson nanofluid flow over an inclined nonlinear stretching sheet along with radiation effects and convective boundaries has been reported yet. The numerical solution of the current problem is obtained using the Keller-box method
