The dynamics of mechanically stressed rotating horizontal convection in a cylindrical enclosure is investigated numerically. The rotating cylindrical container has a differentially rotating base with a thermal forcing applied radially on the bottom boundary. The conditions on the other boundaries are thermally insulated. Axisymmetric numerical solutions showing a steady regime flanked by two unsteady regimes at both ends of the range of Rossby number investigated. The thermally direct mechanical forcing (positive Rossby number) enhances radially horizontal convection, whereas the thermally indirect (negative Rossby number) forcing reverses thermal gradient results in a heated region away from the edge of the container. A robust Nusselt number scaling of ∼ Q1/2 is observed at a high value of Rossby number for both thermally direct and indirect forcing.
