Effects of Hall current and heat transfer on flow due to a pull of eccentric rotating disks

摘要

The influence of Hall current and heat transfer on the magnetohydrodynamic (MHD) flow of an Oldroyd-B fluid is investigated. The fluid is between two infinite disks rotating about non-coaxial axes normal to the disks in the presence of a uniform transverse magnetic field. The flow is due to a constant velocities of eccentric rotating disks. Exact solutions are derived for the velocity, force and torque exerted by the fluid on one of the disk and temperature distribution.
