英文摘要：

The di-actuator theory is modified at the calculation of mass center line, the iteration of radial equilibrium equation, the distribution of inlet velocity, and this theory is used into the design of axial-fan. The performance experiment has been made for this designed fan, the numerical simulation also been made for this fan model. It is proved that the di-actuator theory is a rational model for the design of axial-fan with skew-swept blade in engineering after comparison of these results of the three methods.
