Prediction of unsteady hydrodynamic performance of propeller-rudder systems
摘要
Abstract
Based on the potential theory,a new method to predict the unsteady performance of propeller-rudder systems was developed.Panel method including two lifting bodies in flow field was derived,and the numerical solution was also given.Propeller and rudder were solved,and the interactions between them were considered by the influence coefficients in time domain.The results of steady calculation were taken as initial values of unsteady calculation.The time effects of leak vortex were also considered in unsteady computation.Hydrodynamic performances of the propeller-rudder system in uniform and non-uniform flow were calculated using the integrated method.Results of steady calculation were compared with the experimental values.It can be concluded that the results anastomosis well with the experimental data,and the method with higher at precision can be used in predicting the propeller-rudder system performances.关键词
