High-speed train is developing popular in China, which provides the convenient and fast transportation way, comparable to plane. The moving direction and speed of high-speed train is decided by the traction motor. Generally, a coaxial centrifugal fan is used to cool the motor and assemble in the motor casing. To ensure the reliability of the traction motor, more and more attention is paid to improve the performance of cooling fans in a wide range of rotating speed. As the train is designed to move in both directions, the traction motor is designed to rotate in both directions, so does the coaxial motor cooling fan. Symmetrical and straight blade structure is adopted to get the same performance of the fan in both forward and reverse moving directions. Therefore, the aerodynamic performance of the cooling fan is relatively not good enough, which results in relatively high aerodynamic noise. In order to analyze the cooling fan aerodynamic performance and aerodynamic noise, CFD method was performed on the full 3D model with the impeller-casing clearance. The acoustic analogy method was used to analyze the noise of the centrifugal cooling fan. In addition, the aerodynamic noise of the motor with the cooling fan was tested at different rotating speed in the semi-anechoic lab. The CFD method is verified and the results are in good agreement with the experimental results. The results show that it is necessary to consider the effects of impeller-casing leakage and the vacuum inlet condition in the simulated model to get its more accurate performance. Modified CFD model of the cooling fan was proposed here. It is suggested that the modified structure of the casing can be used to improve the performance of the cooling fan and reduce the corresponding aerodynamic noise.

Axial flow fans are widely used in our daily lives such as automotive cooling systems, electronic appliances and air conditioning. The factors that affect the aerodynamic performance of axial flow fans include blade number, fan diameter, hub ratio, blade angle, rotating speed, etc. This paper investigates effects of hub ratio and bladenumber on the aerodynamic performance of the axial flow fan of the radiator of a dump truck we previously designed for mining. With the computational fluid dynamics (CFD) method, the fans operation condition, such as entry static pressure, effective power and flow rate, are numerically simulated with various hub ratios and blade numbers. The results of the numerical simulations are quantitatively analyzed and curves of fans performance changing with hub ratio and blade number are given. An optimization design for the cooling fan is conducted. The results of numerical simulation give conclusion that an increase of 5.6% of the vacuum static pressure and an increase of 3% of flow rate can be obtained when the hub ratio is between 500-600mm, with the same or even less power consumption. The flow rate increment reaches its peak at 8%, while power consumption efficiency is almost linearly increased, when the blade number increases to be in the range of 8 to 10. That is to say when the blade number is between 8 to 10, the fan is apparently making better use of energy. Compared with experimental method, computational fluid dynamics (CFD) method can reduce design circle and lower cost. The CFD results provide guidance to improvement of design efficiency and energy utilization.
