Prediction of Non-Cavitation Propeller Noise in Time Domain
Abstract：The blade frequency noise of non-cavitation propeller in a uniform flow is analyzed in time domain.The unsteady loading (dipole source) on the blade surface is calculated by a potential-based surface panel method.Then the timedependent pressure data is used as the input for Ffowcs Williams-Hawkings formulation to predict the acoustics pressure.The integration of noise source is performed over the true blade surface rather than the nothickness blade surface,and the effect of hub can be considered.The noise characteristics of the non-cavitation propeller and the numerical discretization forms are discussed. 作者： Author： YE Jin-ming[1] XIONG Ying[2] XIAO Chang-run[2] BI Yi[2] 作者單位： College of Naval Architecture and Power, Naval University of Engineering, Wuhan 430033, China;The Ministry of Education Key Laboratory of High Speed Ship Engineering, Wuhan University of Technology, Wuhan 430033, ChinaCollege of Naval Architecture and Power, Naval University of Engineering, Wuhan 430033, China 期 刊： 中國海洋工程（英文版） ISTICEISCI Journal： China Ocean Engineering 年，卷(期)： 2011, 25(3) 分類號： U664.33 Keywords： propeller surface panel method noise time domain 機標分類號： TV2 TK4 機標關鍵詞： uniform flow noise source integration input time data hub 基金項目： Prediction of Non-Cavitation Propeller Noise in Time Domain[期刊論文] 中國海洋工程（英文版） --2011, 25(3)The blade frequency noise of non-cavitation propeller in a uniform flow is analyzed in time domain.The unsteady loading (dipole source) on the blade surface is calculated by a potential-based surface p...【Prediction of Non-Cavitation Propell】相關文章：
