침수계산에서의 유체의 유출입 모델

Abstract

The calculation method of the amount of floodwater is required, when one simulate the flooding process after damage of ship. The hydraulic model called orifice equation is used widely for that purpose, this works well in the case of small openings. However for the case of large opening, this makes some problems. And this has a weak point for the case that the air and water flow concurrently. This paper surveys the hydraulic model that is relevant to the flood between compartments of a ship. And this study suggests the generalized formula for the calculation of the flux of floodwater, and the calculation method for some special cases.
