| Abstract: | Considering the interaction of uniform advance speed flow and unsteady perturbation flow, the pressure formula from Bernoulli equation has been corrected in order to keep the identity of numerical computations both for predicting ship motion and for determining wave load on the hull surface induced by waves. Based on this pressure formula, a subroutine to calculate the wave load in the computer program system of the hull structure analysis by using FEM named JIFEX95 is developed and some computational examples have shown that the effect of different pressure formulae on the distribution of hydrodynamic pressure on hull surface is obvious and should be taken into account in the marine engineering practice. |
