Abstract
In the current study, we analyze the 2D Williamson nanoliquid flow due to variable thickness surface embedded in permeable space. Cattaneo-Christov heat and mass flux assumptions have been employed for the embodiment of heat and mass equations. Flow is generated by an exponential stretchable sheet. The Darcy-Forchheimer model is considered to scrutinize the liquid flow in a porous medium. The case of prescribed exponential surface temperature of heat transfer is examined. A model is contrived to comprise the partial differential equations and then transform them into ordinary differential equations by imposing an appropriate non-dimensional similarity transformation. The bvp4c technique is used to execute the laborious non-linear equations. A numerical interpretation is manifested to incorporate the skin friction values. The significance of the effect on the involved parameters is presented in graphs and discussed in detail.
