“…Hall current on the fluid flow have many applications in MHD power generation, nuclear power reactors, underground energy storage systems, and in several areas of astrophysical and geophysical interest. Keeping in view of this fact, Jana and Datta [13], Mandal et al [14], Ghosh and Pop [15], Hayat et al [16], Guchhait et al [17], Ghosh [18], Reddy and Bathaiah [19], Das et al [20], Chauhan and Agrawal [21], Seth et al [22,23] and Harisingh Naik et al [24] studied the effects of Hall current on MHD Couette flow of a viscous incompressible electrically conducting fluid in a rotating system considering different aspects of the problem. Hossain [25] studied unsteady hydromagnetic free convection flow near an infinite vertical porous plate with the effect of Hall current.…”
