In this study, we investigate the flows around two S-shaped turbines that rotate inversely by numerical simulation. In general, when analyzing the flow around a rotating object, a rotational coordinate system is often used. However, it is difficult to calculate with such coordinate system when two objects rotate in the reverse direction. Therefore, we use the overset grid that consists of two rotational coordinates for each turbine immersed in a steady coordinate to calculate this turbines' system. In this study, two-dimensional simulation is performed by changing the distance between two turbines rotating inversely, and the influence of interaction is investigated.
