Description

Data center has been built with spread of cloud computing. Further, electric power consumption of it is growing rapidly. High pressure and large flow rate cooling fans are used for servers in the data center and there is a strong demand to increase pressure and flow rate of it because of increase of quantity of heat from the servers. Contra-rotating rotors have been adopted for some of high pressure and large flow rate cooling fans. It is important to clarify unsteady internal flow condition of it for high performance and stable operation. Numerical analysis of high pressure and large flow rate cooling fan with 40 mm square was conducted and unsteady internal flow conditions were discussed in this research.
