Periodic magnetohydrodynamic simulation of Newtonian and non-Newtonian fluids flow behavior past a stretching sheet with nanoparticles

The purpose of this work is to analyse the boundary layer phenomena of Newtonian and non-Newtonian (Casson fluid) nanofluid flow resulting from a stretching sheet with the appearance of periodic magnetic field. Chemical reaction of non-linear order is also considered. The time subservient governing equations such that momentum, thermal and diffusion balance equations are transformed into a convenient dimensionless form by employing finite difference technique explicitly with the support of a programming code namely FORTRAN 6.6.a. However, a stability and convergence test is also performed for the accurateness of the above mentioned numerical technique and the existing work is found converged for Prandtl number, Pr ≥ 0.048 and Lewis number, Le ≥ 0.016. Furthermore, the impact of diversified physical parameters on various flow fields are presented graphically and also discussed through tabular analysis. Finally, for the validation of the existing work, the current results are compared with the published results and a favourable agreement is attained.
