Abstract
The present analysis deals with the study of time-dependent flow of a second-order fluid on a rotating cone in the presence of chemical reaction and heat generation or absorption effects under prescribed heat flux conditions. The boundary-layer nonlinear partial differential equations of second grade fluid are first reduced into a system of ordinary differential equations with the help of transformations and nondimensional similar and nonsimilar quantities, and then solved analytically by optimal homotopy analysis method (OHAM). The effects of relevant parameters such as chemical reaction, heat generation, or absorption on local skin friction coefficients, local Nusselt number, and local Sherwood number are discussed. These effects are illustrated graphically as well as in tabular form to describe special features of the solutions.
