| Abstract: | Based on the rotary symmetry of a fan impeller, the characteristic equations of the impeller in each irreducible subspace are derived in the paper by using the Cn group representation theory. Because the order of the equations is quite low so they are easy to compute and convenient to use in engineering applications. In addition, the modal characteristics of the structure can also be obtained by the method. |
