Estimation of orifice flow rates for flooding of damaged ships
Estimation of orifice flow rates for flooding of damaged ships
This paper concentrates on the modelling of compartment flooding rates following the occurrence of damage. Typical state of the art flooding models use Torricelli.s formula to calculate flooding rates using a constant co-efficient of discharge (Cd). Based on Bernoulli.s theorem, turbulence and viscosity effects are not included using a Cd independent of damage shape or size. Previous work indicates that this assumption over-simplifies the problem to an extent where the flooding rates used for calculation are in error. Simple validation of a tool to assess flow rates for emergency response is included.

Abstract
This paper concentrates on the modelling of compartment flooding rates following the occurrence of damage. Typical state of the art flooding models use Torricelli.s formula to calculate flooding rates using a constant co-efficient of discharge (Cd). Based on Bernoulli.s theorem, turbulence and viscosity effects are not included using a Cd independent of damage shape or size. Previous work indicates that this assumption over-simplifies the problem to an extent where the flooding rates used for calculation are in error. Simple validation of a tool to assess flow rates for emergency response is included.
