The Pien Wavemaking Resistance Computation Program Part 1. Theoretical Basis and Programming Technique

Abstract : The waves produced at the rear of a ship as it travels at the water's surface are directly related to a component of the ship resistance known as wavemaking resistance. Pien's 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. This computer program can also be used in determining the optimum hull form which has the least theoretical wavemaking resistance. Applied initially for the development of small waterplane area twin hull and single hull ships, the Pien program produced predicted wavemaking resistances which compared favorably with those measured from actual experimental model tests.
