内容記述 | We proposed prediction methodology of broadband noise generated from a low-pressure fan based on the pressure power spectrum density (PSD) of a flat plate determined experimentally. Although the predicted broadband noise by the pressure PSD was evaluated 12.5 dB larger than the measured value, it could represent the measured spectral distribution. In the tip side of the blade, even if the relative velocity of the wake decreased, the broadband noise of the blade element was larger than the mid span domain where the relative velocity was high. We indicated that the increase of the broadband noise at the blade tip was due to the normalized pressure PSD became larger than that one at the mid-span. | |||||
