A mathematical analysis of time dependent flow on a rotating cone in a rheological fluid

Abstract

In the present study we have explored the time dependent combined convectional flow on a rotating cone in a rotating Jeffrey fluid with the combined effects of heat and mass transfer. The governing equations of motion, energy and mass transfer for unsteady flow are presented and simplified using similar variables. The reduced coupled nonlinear differential equations are solved analytically with the help of strong analytical technique homotopy analysis method. The heat transfer analysis for prescribed wall temperature is considered. Numerical results for Nusselt number and Sherwood number have computed and discussed. The physical features of pertinent parameters are discussed by plotting the graphs of velocity, heat transfer, concentration, skin friction, Nusselt number and Sherwood number.
