| Abstract: | This effect of pressure gradient on flood port resistance is studied,orthogonal and uniform design methods are used to draw up the calculation schemes,two empirical equations for flood port resistance coefficient are presented by way of stepwise regression.In order to validate the utilities of the two equations,the flood port allowances of a active submarine are calculated.A new prediction method for the submarine flood port allowances is developed. |

| Keywords: | computational ship hydrodynamics submarine flood hole flood port resistance coefficient flood port allowance |
