| Abstract: | Based on the numerical method of desingular dissipative Green′s function integral,a compuational model of free surface wave elevation under uniform flow passing double-point sources is established in this paper.The variation of free surface wave elevation and the profile of the wave contour are presented with the different dissipation parameters,froude number and different distances between the double sources.The numerical simulation results are verified and compared with the previous numerical results by the desingularity dissipative Green′s function and double sources,and the numerical results agree well with the previous papers. |
