舵空泡对船体压力脉动的数值分析
Numerical analysis of hull pressure fluctuation by rudder cavitation
摘要
Abstract
[Objectives]In order to demonstrate the serious vibration and noise rules of a ship's rudder surface,the pulsation pressure of the rudder cavitation is studied and analyzed. [Methods] Using Star-CCM fluid calculation software to simulate the test results under working conditions of rudder angle at 5 and 10 degrees respectively,and at a certain speed,rudder cavitation forecasting and hull pressure fluctuation regularity analysis are carried out. [Results]It is found that the pulsation of the rudder cavitation has a direct impact on hull pressure fluctuation;with a rudder angle of 5 or 10 degrees,the amplitude of the hull pressure fluctuation caused by the rudder cavitation is greater than when there is no cavitation in the rudder's surface. The more severe the rudder cavitation,the greater the amplitude of the hull pressure fluctuation.[Conclusions]The results demonstrate that the rudder cavitation has a direct impact on the vibration and noise of a ship.关键词
