Impact of gold and silver nanoparticles in highly viscous flows with different body forces

The present investigation is relevant to the multiphase flow of non-Newtonian fluid passing through the steep channel. Third-grade fluid is taken as the base liquid, while two different types of metallic particles are considered to form nano-suspensions. Two different plane flows are devised based on the development of rigid walls of the inclined channels. A comprehensive apprehension regarding the nonlinear flow dynamics is carried out with the help of a regular perturbation method, which is effectively less time-consuming and more analogous to analytic. Moreover, a comparative analysis depicts complete harmony with the existing literature. In addition, the current study reduces back to the customary nanofluid problem for the limiting case.
