Study on Influence Factors of Nominal Wake of Full-formed Ships
Taking full-formed bulk carriers as the research object,numerical simulations of nominal wakes are carried.Strategy is determined with the existing wake test data.Numerical simulations are carried out on 27 target ships,nominal wakes of which are obtained.A clustering analysis algorithm is applied to obtain three categories of wakes.A calculation method of the characteristics of the lines is established,and the wake category and wake value are analyzed according to the characteristics of the ship's stern cross sections and waterlines.The results show that the combination of the waterlines in front of the propeller has a significant effect on the wake.Regression analysis can accurately predict the average wake value.
