报告摘要：An analysis regarding diverse features of Sisko fluid flow over a curved stretching surface in the presence of magneto-nanoparticles is presented. For the larger value of the curvature parameter, the curved surface reduces into the planner sheet. The governing equations are modeled in the curvilinear coordinate system and transformed into nonlinear ordinary differential equations. The obtained equations are solved numerically by employing the boundary value solver (bvp4c) in Matlab and bvp traprich in Maple. From the obtained results, we observed a decline in the magnitude of the velocity field and pressure inside the boundary layer with increasing values of magnetic parameters. On the other hand, the temperature of the fluid is noticed in enhancing trend with growing values of Brownian motion and thermophoresis parameters. Moreover, concentration is also to be growing with augmented values of the Schmidt number. A comparison for validation of the present results is performed between the bvp4c function in Matlab and the Richardson extrapolation method in Maple with an excellent agreement. The results are also verified with previous works.
