The comparison showed that : ( l ) farassat 1a formula is the simplest one and work well for the subsonic rotor . ( 2 ) both kirchhoff formula and k - fwh formula can predict the nonlinear noise generated by transonic rotor ; ( 3 ) when the surface is not positioned in the linear region , kirchhoff approach for rotating integration surface could lead to substantial error , but k - fwh formula can still work well 数值研究表明: farassat1a公式在预测线性噪声方面简单有效,适用于亚音速旋翼的噪声预测; kirchhoff公式和k - fwh公式均能够预测跨音速旋翼声场,并且具有较高的精度;当声源面位于流动非线性时, kirchhoff公式会导致很大的计算误差,而k - fwh公式不存在这样的问题。
