<p>Torque and flow pattern of gas-liquid two-phase flow driven by a rotating body are numerically studied. Two-dimensional direct numerical simulations are performed using a fixed mesh approach based on Volume Of Fluid (VOF) and Boundary Data Immersion (BDI) methods. We investigate the influence of rotational speed Ω, fluid properties, and rotating body shape. The interplay between the centrifugal and gravitational forces gives rise to transition of the flow pattern with Ω, that is qualitatively similar for all the body shapes chosen in the present study. The rotational speed of the transition to the annular flow in the non-axisymmetric system is found to be lower than that in the axisymmetric system. The flow structure is classified into four patterns with respect to the torque and the contact ratio of liquid phase at the rigid body interface. The torque and the contact ratio are found to be scaled by the Froude number.</p>
