ON THE 3-D PULSATING SOURCE OF MICHELL'S TYPE WITH FORWARD SPEED

An expression of the Michell type 3-D pulsating source with forward speed for infinite water depth is derived in this paper, based on the Fourier transformation and contour integration technique. The feature of the source and the radiation behaviour far from the source is discussed. The relative importance of each component of the pulsating source is discussed in detail. Compared with the commonly used pulsating source of the Haskind type, the expression has the merits of simplicity for numerical treatment and is more meaningful in its physical explanation. The Michell type expression of the 3-D pulsating source with forward speed can be widely used for the estimation of motions and wave forces for ships and offshore structures in waves with forward speed. The radiative behaviour of the source in the far field may also give a reasonable description of the radiation condition or the open boundary condition for other numerical methods, such as the Rankine source method, etc.
