Abstract

An exact solution is obtained for the magnetohydrodynamics (MHD) flow of a conducting, incompressible Oldroyd-B fluid between two infinite, parallel, insulated disks rotating about non-coincident axes normal to the disks in the presence of a uniform transverse magnetic field. The effects of the Hartmann number M, the Deborah number D, the Reynolds number R and the elastic number alpha on the velocity field and the force are discussed. It is found that the value of the torque exerted by the fluid on one of the disks is zero. (C) 1999 Elsevier Science Ltd. All rights reserved.
