For suppressing the automotive troubles like an overheating of the drum/disc brake units or the in-wheel motor devices, authors propose the new automotive wheel with the blade shape spokes, which can work as the cooling fan, by use of the blade design procedure of the turbomachinery. In this paper, the prototype automotive wheels with the centrifugal or axial type blades were prepared to confirm the flow generation by proposed wheels experimentally and numerically, as the preliminary step. The proposed wheel brings the increase of the air flow through the wheel compared with the traditional wheel, which has the rectangle shape spokes. At a same time, the required power for the rotation wheel rotation with cooling fan also increase about 2-4% of the traditional one. Furthermore, the swirling inlet flow, which generates by the rotating cylindrical rim, may greatly influences the discharge performance of the wheel with the axial blades.
