| Description | Small-sized axial fans are used as air cooler for electric equipments. But there is a strong demand for higher power of fan according to the increase of quantity of heat from electric devices. Therefore, higher rotational speed design is conducted although, it causes the deterioration of efficiency and the increase of noise. Then the adoption of contra-rotating rotors for small-sized fan was proposed for the improvement of performance. In the present paper, the performance and internal flow condition of a small-sized axial fan with 100mm diameter are shown as a first step of the research for the contra-rotating small-sized axial fan and the similarity law of this small-sized axial fan is discussed. Furthermore, the numerical flow simulation was conducted to investigate the performance of the contra-rotating small-sized axial fan and internal flow field and pressure distributions were clarified and the effect of contra-rotating rotors would be considered. |
