Analytical treatment of unsteady mixed convection MHD flow on a rotating cone in a rotating frame

In this article, we have examined the unsteady mixed convection flow of magnetohydrodynamics (MHD) flow on a rotating cone in a rotating frame. The governing equations of motion in curvilinear coordinates system in the presence of MHD and convection are given. The highly nonlinear differential equations are reduced with the help of similarity transformations and the boundary layer approach. The solutions of reduced equations for rotating cone boundaries are established analytically with the help of homotopy analysis method. The heat transfer analysis for prescribed wall temperature and prescribed heat flux are considered. The expressions for velocity, temperature and concentration are computed and discussed through graphs for various emerging parameters. (c) 2013 Taiwan Institute of Chemical Engineers.
