摘要:According to the forming reason and classification of the hull resistance, this paper puts forward a three dimensional RANS method to solve the wave-making resistance. The obtained numerical results are compared with the results obtained from numerical program based on Rankine source boundary element method and the results obtained from Experimental fluid dynamics (EFD) method. The conclusion is drawn that the three dimensional RANS method matches well with EFD method, and its accuracy is higher than Rankine source method. From the results of the used methods it appears that the value of shape factor (1+k) for three dimensional RANS method is slightly increased with the increase of Froude number, the free surface wave system of three dimensional RANS conforms to the characteristics of the Kelvin wave system, the height of wave crest for three dimensional RANS method is bigger than Rankine source method, while the wave trough is lower, and the variation tendency of wave profile based on three dimensional RANS method is almost the same with Rankine Source method. The proposed method is proved to be appropriate for engineering application.
