槳葉面積 的英文怎麼說
中文拼音 [jiǎngyèmiànjī]
槳葉面積
英文
blade area-
Airscrew blade area
螺旋槳葉面積The unknown source strength of cavitation is always arranged on the propeller blade surface in the solving process, but the integration is carried out along the cavity surface of last iterative step when the strength of cavitation dipole is determined according to dynamic condition
求解過程中待求的空泡源強始終布置在槳葉表面上，而在根據動力學條件求解每一步的空泡麵元偶極子強度時，積分是沿著上一步迭代確定的空泡表面進行的。Presently most of the theoretical method to predict the propeller - induced hull pressure fluctuation is based on the calculation method in which the pressure is induced by pulsating source in infinite flow. the calculation method is adopted and the corresponded computer program is complied. the propeller - induced hull pressure fluctuation due to blade thickness, blade load, cavity thickness and the change of the cavity volume can be analyzed respectively in the computer program
目前，螺旋槳誘導的船體表面脈動壓力的理論預報方法，大多是以無限流場中點脈動源誘導的周圍流場的脈動壓力的計算方法為基礎的，本文採用該方法編制了計算程序，可以分別考慮槳葉厚度、槳葉負荷、槳葉上空泡厚度及其體積變化在船體表面指定位置上產生的脈動壓力。
