Abstract
Nanofluid flow towards a nonlinear stretched Riga plat of varying thickness is considered in this study. Riga plate is an electromagnetic sheet containing electrodes at fixed positions alternatively. This pattern causes an electromagnetic effect in nanoliquid flow. The flow develops due to the nonlinear stretchable Riga plate. Mathematical modelling and analysis are carried out in the presence of Joule heating, slip effect and heat generation. Brownian motion and thermophoresis aspects for nanoliquid are incorporated using Buongiorno's model. Resulting nonlinear partial differential equations are transformed into nonlinear ordinary differential equations using suitable similarity transformations. Homotopy analysis method is used for series solutions. Convergent of series solutions are analyzed for momentum, energy and concentration functions. Drag coefficient and heat transfer rate are modelled and presented. The findings of analysis show that the modified Hartman number enhances the velocity profile. Opposite behavior is seen for velocity and temperature against variable thickness parameter. Heat transfer coefficient declines for larger Brownian motion and thermophoresis variables. The comparison of current study with published data is presented.
