Insight of Riga effects on dynamic of Prandtl nanofluid over a moving wedge via Keller box approach

Abstract

The magnetohydrodynamic flow of Prandtl nanofluid due to stretching/shrinking Riga wedge with activation energy is investigated. The stagnation point flow is attributed to suction/injection in the presence of heat sources. Enhancement in thermal transportation of the base fluid attracted our attention to increase thermal conductivity. Prandtl fluid formulation pertains to the 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 to provide results for the flow field, thermal distributions and concentration field. The controlling parameters are varied in their suitable range to exhibit their role as graphical and numerical. Velocity profile is increased directly with larger values of material parameter while for elastic parameter , it shows decreasing trend. The skin friction is boosted with the increasing values of magnetic parameter at the fluctuation of . The aspect of physical explanation, flow nature is elaborated graphically and numerically.
