The present analysis examines the combined effects of Hall currents and thermal radiation on unsteady MHD hybrid nanofluid flow in a rotating vertical channel. Closed form solutions are obtained after simplification and suitable consideration. Cu and CuO nanoparticles are chosen for manufacturing of hybrid nanofluid. Analysis is carried out for three different stable shapes of nanoparticles. It is concluded that brick shaped nanoparticles contribute to relative low temperature distribution while platelets shaped nanoparticles are efficient in a sense of rising fluid flow. Moreover, primary velocity is a decreasing function of rotation parameter while secondary velocity is an increasing function of K2. Both velocities lessen with the rise in thermal radiation near the left wall while their magnitude rises near the right wall of the vertical channel.
