Analytical Study of Rotating Non-Newtonian Nanofluid on a Rotating Cone

摘要

Unsteady mixed convection flow of a rotating second grade nanofluid in a rotating cone is investigated. The governing coupled nonlinear partial differential equations are reduced to nondimensional form with the help of similarity transformations, and then solved analytically with the help of the homotopy analysis method. Two cases of heat transfer are taken into account namely 1) prescribed wall temperature and 2) prescribed heat flux. The effects of relevant parameters on the velocity, temperature, concentration, skin friction coefficients, Nusselt number, and Sherwood number have been examined graphically. At the end, a comparison of our analytical results and previous numerical results is presented.
