Abstract
The effects of Hall current on Couette flow and heat transfer of a conducting fluid between two plates in a rotating system are discussed. Both Hall and rotation parameters introduce secondary velocity and secondary induced magnetic field. The resultant shear stress and heat transfer from the moving plate has been calculated assuming it to be non-conducting and taking the fixed plate to be infinitely conducting. The resultant shear stress increases with increase in Hartmann number as well as rotation parameter while it decreases with increase in Hall parameter. The role of each parameter on heat transfer is always opposite to its role on shear stress. In the absence of Hall current this opposing character remains unalterned even if direction of rotation is reversed.
