Numerical investigation for MHD Prandtl nanofluid transportation due to a moving wedge: Keller box approach

Abstract

Magnetohydrodynamic flow of Prandtl nanofluid due to stretching/shrinking wedge with activation energy is investigated. The stagnation point flow is attributed with suction/injection in the presences of heat sources. Enhancement in thermal transportation of the base fluid attracted our attentions to increases thermal conductivity. Prandtl fluid formulation pertains to novelty of this work. The boundary layer approximations are considered for the governing equations to be contortioned in the form of partial differential equations. Appropriate similarity transforms are employed to attain the boundary value problem in ordinary differential form. Then Keller-box method is utilized to gain numerical suction for to provide results for flow field, thermal distributions and concentration field. The controlling parameters are varied in their suitable rang to exhibit their role as graphically and numerical. Velocity profilef′(ζ) is increased directly with larger values of material parameter α while for elastic parameterβ, it shows decreasing trend. The skin friction−f′(ζ)is boosted with the increasing values of magnetic parameter.
