基于2D+t势流方法的滑行艇静水姿态预报研究
Study on attitude prediction of planing hull in calm water based on 2D+t potential flow method
摘要
Abstract
To predict the motion attitude and the vertical force distribution of the planing hull in calm water,by using 2D+t potential theory,the direct navigation problem of a planing hull was transformed into the water entry slamming problem of a two-dimensional section,and a time-domain model was established to predict the attitude of planing hull in calm water.The modified Logvinovich model(MLM)was utilized to calculate the slamming load of the two-dimensional planing hull section,and a correction method was proposed to make up the deficiency of 2D+t theory in predicting the hydrostatic pressure and the hydrodynamic pressure of planning hull near bow and stern region.For the restricted ship model,the vertical force distribution results of modified 2D+t method are in good agreement with that of the three-dimension computational fluid dynamics(CFD)method.For the free ship model,the motion attitude results of modified 2D+t method are in good agreement with that of the experiment.The high prediciton accuracy of the modified 2D+t method for the hydrodynamic problem of planing hull in calm water was verified.关键词
