Time Domain Computation of the Wave making Resistance of Ships

摘要

A linearised three-dimensional potential flow formulation in time domain is applied to calculate wavemaking resistance of ships in calm water. Steady state perturbation potentials for resistance are obtained as the steady state limit of the surge radiation impulse response function using the transient free surface source distribution over the body surface. Three different vessels are used to validate the present numerical approximation. The results including steady state wave making resistance, sinkage force, trim moment and wave profile along waterline are compared with other published numerical and experimental results.
