| Numerical analysis for prediction of flow rate of the motor cooling fan Tae In Kang
The Journal of Mechanical Science and Technology, vol. 22, no. 10, pp.1870-1875, 2008
Abstract : In this study, we analyzed the three dimensional unsteady flow around a motor cooling fan using the vortex panel
method. For a popular type of motor cooling fan that has thin blades, we predicted the flow rate through numerical
analysis without experimental data, such as the free stream velocity, which is a boundary condition of the flow field.
We also calculated the flow rate for various cooling fan geometries and rotating speeds. For these fans, the numerical
results showed flow rates within 3% of the experimental results.
