摘要：
A moving flux source is modified to predict ship waves by using NOWT-PARI (NOnlinear Wave Transformation model by the Port and Airport Research Institute), taking into account the expandability of setting ship navigation channels and applicability for representative ship shape in a harbor. The fluxes on a slender-ship sailing are generated with two functions approximating ship shape: a modified parabolic function and an interpolation of Lewis form. Through several sets of numerical simulations reproducing ship waves measured in model experiments, a tuning parameter related to the ratio of ship width and length to computational mesh size is introduced in order to secure independence of the calculation accuracy of ship waves from a spatial resolution.
