چکیده:

Flow fields and wave patterns are computed in the far field of a ship moving steadily, using Michell’s thin-ship theory. Having the wave records in far field, the wave resistance and also total resistance of ships are computed. Computed ship resistances are compared with experimentalesults in different depths in shallow water. The numerical simulation is performed in subcritical, critical and supercritical regimes for different depth Froude numbers. However for the accuracy of simulation the effect of eddy viscosity is then considered. This method can be applied for
conventional ships with great accuracy and reliability.
