中文摘要：
研究桥墩对桥区航行船舶的干扰水动力,对正确地控制船舶航迹以保证船舶安全通过桥区,具有重要的参考意义。文章基于CFD软件Fluent,采用准定常和非定常两种方法,通过数值模拟在桥墩邻域航行船舶的粘性绕流场,计算分析了桥墩对船舶的干扰水动力特性。数值结果表明,桥墩对船舶的干扰水动力与船与桥墩的相对位置紧密相关,船舶在桥墩邻域一定的范围内航行时,桥墩干扰水动力明显。
英文摘要：
In order to control ship＇s trajectory properly to guarantee passing the bridge area safely,investigation of the hydrodynamic interference forces on ships induced by bridge piers has an important reference value. Based on the CFD code Fluent, this paper adopts quasi-steady and unsteady methods to numerically simulate the viscous flow field around a ship navigating in bridge area, and to calculate and analyze the characteristics of the hydrodynamic interference forces. The numerical results show that the hydrodynamic interference forces on the ship induced by the neighboring pier are closely related to the relative position between the ship and the pier. The hydrodynamic interference forces are remarkable when the ship is navigating within a certain range of area near the pier.
