| Summary: | The current study delves into the analysis of 3-D flow of a Casson nanofluid over a convectively heated stretching sheet. This investigation takes into account the effects of non-Fick’s mass and non-Fourier heat flux. An efficient semi-analytical technique called homotopy analysis method (HAM) with BVPh2.0 package is utilized to obtain the series solution and calculate the residual errors of the governing system of equations. Influences of the flow governing parameters were examined through graphs and tables. The influences of the different arbitrary constants in velocity, temperature, and concentration profiles were graphically shown and interpreted while the friction coefficients, Nusselt number, and Sherwood numbers were numerically evaluated. It is found that the Prandtl number Pr and the temperature profile θ(η) are inversely related, while the Biot number, the magnetic and Casson fluid parameters, M and β are all favorably correlated. The Casson parameter β and the magnetic parameter M have positive effects on the concentration profile φ(η) whereas Prandtl number Pr has a negative effect. When the Casson fluid parameter is raised, the skin friction coefficient decreases. On the contrary, at increasing values of the Prandtl number Pr, the local Nusselt number drops. In addition, the local Sherwood number decreases as the Brownian motion parameter rises.
