The Pien Wavemaking Resistance Computation Program. Part 2. Users Manual.
Abstract
The waves produced at the rear of a ship as it travels through the water's surface are directly related to a component of the ship's resistance known as wavemaking resistance. The Pien Wavemaking Resistance Computation Program adapts Havelock's mathematical representation of this phenomenon to provide the ship designer with a relatively quick and inexpensive way of determining the wavemaking resistance of his proposed design. The program can also be used in determining the optimum hull form which has the least theoretical wavemaking resistance. The Pien program has been used in the development of small waterplane area twin-hull ships and small waterplane area single-hull ships. The wavemaking resistances estimated by the Pien program compare favorably with those measured in actual experimental model tests. The use of the Pien program for the design of other type ships seems promising. The Pien program has been written in CDC FORTRAN Extended and developed for use on the CDC 6000-series computers. The theory underlying the logic of the program has been documented in Naval Ship Research and Development Center Report 4370, 'The Pien Wavemaking Resistance Computation Program - Part 1: Theoretical Basis and Programming Technique.' The use of the program is described in this report. (Author)
