| Abstract: | Based on the k-ε turbulent flow model and three-dimensional time averaged N-S equation,a three-dimensional permanent turbulent flow calculation of the whole flow field was performed of mixed-flow fans,many important flow phenomena,such as pressure distribution and velocity distribution in fans,were obtained.The result shows that the computational fluid dynamic analysis of the whole flow field of fans can comparatively accurately predict the flow field structure in fans. |
