  2. 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,誘導的船體表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,可以分別考慮厚度、負荷、上空泡厚度及其體變化在船體表指定位置上產生的脈動壓力。
