Free Convective MHD Jeffrey Fluid Flow between Two Coaxial Inclined Permeable Cylinders

MHD free convective flow of a Jeffery fluid between two coaxial inclined cylinders has been investigated by using the quadratic density temperature (Q.D.T) relationship. The inner and outer cylinders are permeable. Applying perturbation method the velocity and the temperature fields are obtained. The effects of heat source parameter, permeability parameter, Jeffrey parameter and Hartmann number on the velocity and temperature distributions are discussed in detail. The magnitude of velocity increases with the increasing permeability parameter σ whereas the magnetic field reduces the velocity in the annulus of two permeable cylinders.
