Numerical simulation of periodic MHD casson nanofluid flow through porous stretching sheet

摘要

The perspective of this paper is to characterize a Casson type of Non-Newtonian fluid flow through heat as well as massconduction towards a stretching surface with thermophoresis and radiation absorption impacts in association with periodichydromagnetic effect. Here heat absorption is also integrated with the heat absorbing parameter. A time dependentfundamental set of equations, i.e. momentum, energy and concentration have been established to discuss the fluid flowsystem. Explicit finite difference technique is occupied here by executing a procedure in Compaq Visual Fortran 6.6a toelucidate the mathematical model of liquid flow. The stability and convergence inspection has been accomplished. It hasobserved that the present work converged at, P_r ≥ 0.447 indicates the value of Prandtl number and L_e≥ 0.163 indicatesthe value of Lewis number. Impact of useful physical parameters has been illustrated graphically on various flow fields. Ithas inspected that the periodic magnetic field has helped to increase the interaction of the nanoparticles in the velocityfield significantly. The field has been depicted in a vibrating form which is also done newly in this work. Subsequently,the Lorentz force has also represented a great impact in the updated visualization (streamlines and isotherms) of theflow field. The respective fields appeared with more wave for the larger values of magnetic parameter. These results helpto visualize a theoretical idea of the effect of modern electromagnetic induction use in industry instead of traditionalenergy sources. Moreover, it has a great application in lung and prostate cancer therapy.
