Multi-disciplinary optimization of a contra-rotating fan

International Journal of Aeroacoustics, 2018
This paper presents the shape optimization of the blades of a contra-rotating fan according to aerodynamic, structural and aeroacoustic criteria. The prediction of wake-interaction and trailing-edge noise emission is integrated into the optimization process by means of RANS-based hybrid methods.

Unsteady flow condition of contra-rotating small-sized axial fan

Journal of Thermal Science, 2011
Small-sized axial fans are used as air cooler for electric equipments. But there is a strong demand for higher power of fans 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.
