| Abstract: | Amethod for predicting the noise generated by rotor wake-stator interaction is presented by solving the generalized Lighthill equation in the paper.First of all, a wake model behind the rotor blades is given. Then, the unsteady forces on the stator blades can be computed, using a 2-dimensional compressible unsteady computation method. At last, the rotor stator interaction noise is obtained, considering the effects of the compressor tube on the noise fields. The total noise power depends on the following parameters: stagger angle and chord of stator blade, spacing of rotor/stator, Ma number, rotor speed and wake modle behind the rotor blades.Some numerical results are given to analyse the effect of the spacing of rotor-stator on the noise radiation. The estimated results show a reasonable agreement with the experiment tal data. |
