Flow of Power Law Fluids between Two Rotating Co-Axial Cones

The problem of fluids flow between two coaxial cones has important applications in the theory of hydrodynamic lubrications and in the measurement of viscosity coefficients. In a recent paper Rathy has discussed the flow of a Newtonian fluid between two coaxial rotating cones with a common vertex under a radial force. In the present paper an exact analytical solution of the flow behaviour of power-law fluids between two coaxial rotating cones under the action of a radial force, has been obtained
