Flow of magneto Williamson nanoliquid towards stretching sheet with variable thickness and double stratification

Double stratification in stagnation point flow of magneto Williamson nanoliquid towards nonlinear stretching sheet of variable thickness is explored. Flow is stretched in non-linear way since the sheet is assumed not flat. Aspects of viscous dissipation and radiation are accounted. First order chemical reaction is also present. Proper transformations lead to dimensionless the problems. Resultant problems is analytically solved via homotopic technique. Convergent solutions are obtained. Graphs and table are arranged to manifest the behavior of various influential variables. Our analysis pointed out that stratification variables diminishes the temperature and concentration. Moreover skin friction is decayed for larger magnetic parameter. Finally, conclusion of current investigations are listed in the last section.
