The present analysis examines the MHD rotating transport of CNTS in a vertical channel submerged with Hall current and oscillations. We have modeled this problem in a rotating frame. The governing equations are derived and simplified into dimensionless form using suitable non-dimensional variables. Moreover, modelling of the problem is completed by incorporating Hall current and temperature oscillation at the boundary. In addition, closed form exact solutions are derived for both velocity and temperature profiles. Single-walled (SWCNT) and multi-walled (MWCNT) carbon nanotubes are taken into account. The effects of pertinent parameters are studied through graphs. It is concluded that the transverse magnetic field is a resisting force which contributes in lowering fluid velocity. Furthermore, for SWCNT and MCWNT nanofluids, this trend remains the same. Moreover, the comparative study between SWCNT and MWCNT nanofluids reveals a slight increase in the temperature of the SWCNT nanofluid for rising values of R , and n .
