COMPUTATIONS OF 3D TRANSOM STERN FLOWS

The theory and numerics of computing 3-D transom stern flows are described in detail. The transom is treated as an inflow boundary, and the transom boundary condition is then used to specify the starting values of a linearized free-surface calculation. This computational method has been incorporated into a Rankine source panel method and integrated into the XYZ Free Surface (XYZFS) program version 2.0. The XYZFS program has been used to predict the wave resistance for a large number of transom stern ships. The computed wave resistance compares favorably with the measured wave pattern resistance, correctly predicting the relative merit of competing hulls. The agreement with experimental measurements is remarkably good for Froude numbers between 0.35 and 0.50, values corresponding to the normal speed range of high-speed transom stern ships.
