    文摘:應用基於多波長消光法原理發展的光學探針,測量了風洞中不同馬赫數濕空氣流自發凝結形成的水滴尺寸及濃,並給出了實驗結果。
  2. 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

    數值研究表明: farassat1a公式在預測線性噪方面簡單有效,適用於亞音旋翼的噪預測; kirchhoff公式和k - fwh公式均能夠預測旋翼場,並且具有較高的精;當源面位於流動非線性時, kirchhoff公式會導致很大的計算誤差,而k - fwh公式不存在這樣的問題。
