【Abstract】 The design method of"free-vortex flow" axial fan using quasi-similarity theory(inner or outer radius not following geometry similarity theory) has been researched in this paper,and the general formulas for performance calculation has been derived. In this way, a few model stages with excellent performance can be used to expand the parameters range of aerodynamic performance of axial fan, to meet many kinds of engineering requirements, and to achieve performance optimized design.更多还原
