摘要:

螺旋桨在紧急倒车工况下的水动力特性与船舶的紧急制动能力密切相关并直接影响船舶的航行安全性.基于开源计算流体动力学平台OpenFOAM中的雷诺平均求解器对螺旋桨在紧急倒车工况下的水动力特性及绕流场开展数值研究.以5叶螺旋桨DTMB4381模型为研究对象,对其正车前进以及紧急倒车工况进行数值模拟.通过与国际上公开的模型试验结果进行对比,验证了所采用的数值方法在预报螺旋桨不同工况下水动力性能方面的有效性.基于数值模拟获得的水动力载荷及流场信息,探讨了紧急倒车工况下局部绕流场特征随进速变化的规律及其与螺旋桨整体水动力特性之间的关系,为船舶紧急倒车制动能力评估提供了理论依据.

Abstract:

The hydrodynamic characteristics of a propeller under the crashback condition are closely related to the crash stopping ability of a ship, which directly affect the ship navigational safety. In this paper, a numerical study on the hydrodynamic characteristics of a propeller and the flow field around the propeller under the crashback condition is conducted based on the Reynolds-averaged Navier-Stokes solver in the open source computational fluid dynamics platform OpenFOAM. Taking the 5-blade propeller DTMB4381 model as the study object, the ahead and crashback conditions are numerically simulated. The numerical results are compared with international open model test data to validate the effectiveness of the numerical method in the prediction of the hydrodynamic characteristics of the propeller under different conditions. Based on the obtained hydrodynamic loads and flow field details, the local flow field characteristics changing with the advance velocity and the relation between the local flow fields and the global hydrodynamic forces are explored, which provides theoretical basis for the evaluation of ship crash stopping ability.

Key words: propeller crashback, hydrodynamic characteristics, computational fluid dynamics (CFD), OpenFOAM, Reynolds-averaged Navier-Stokes (RANS) method
