浅水区域船舶航行下沉量的数值计算

Numerical calculation of ship sinking in shallow water

船舶在浅水区域航行过程中,受水流和压力的影响,下沉量相对于深水区域有较大的变化,浅水效应的出现对于船舶有不利的影响,会增大船舶触底的风险,特别是目前船舶吨位不断加大,浅水效应更加明显。针对这一问题,本文建立船舶航行的下沉量模型,基于CFD计算流体理论对船舶在浅水区域的下沉量特性进行研究。

During the navigation in the shallow water area,due to the influence of the current and pressure,the sinking of the ship has a great change compared with the deep water area.The appearance of the shallow water effect has a negative impact on the ship,which will increase the risk of the ship hitting the bottom,especially with the increasing tonnage of the ship,the shallow water effect is more obvious.In order to solve this problem,this paper establishes a ship's sinking model,and studies the characteristics of ship's sinking in shallow water based on CFD computational fluid theory.
