ABSTRAKT

The two-dimensional triple-diffusive boundary layer slip flow of nanofluid over a nonlinear stretching sheet embedded in a porous medium is scrutinized in the concerned study. The model used for the nanofluid incorporates the effects of thermophoresis, Brownian motion, cross-diffusion, and the power law stretching parameter. A uniform magnetic field of strength B0 is applied perpendicular to the flow direction. Using suitable similarity transformations, governing partial differential equations were reduced to higher-order ordinary differential equations and are solved by using the Matlab bvp4c package. Concrete graphical analysis is carried out to study the effects of different emerging parameters on velocity, temperature, solute, and nanoparticle concentration distributions coupled with a comprehensive discussion. Furthermore, the Nusselt number, the Sherwood number, and the nanofluid Sherwood number are derived and discussed graphically.
