摘要

传统的螺旋桨水动力性能研究主要针对静水条件,但船后工作的螺旋桨经常会受到波浪的影响.从文献情况来看,目前与波浪中螺旋桨水动力性能相关的研究工作相对较少.有鉴于此,采用基于OpenFOAM的雷诺平均NS(RANS)求解器,计算、分析波浪对螺旋桨推力及转矩的影响.研究结果表明:在波浪的作用下,螺旋桨推力及转矩的时间历程曲线发生振荡,且随着浸深与进速系数减小,水面扰动变大,时历曲线的振荡幅度增大;与静水条件相比,在浸深与进速系数相同的情况下,波浪中螺旋桨推力及转矩的平均值减小;计算结果与现有的试验数据吻合良好.

Abstract

The hydrodynamic performance of propeller is mostly studied in calm water, but the propeller working behind ship is often affected by waves. According to the literature, there is relatively little research on hydrodynamic performance of propeller in waves at present. In view of this, RANS solver based on OpenFOAM is used to calculate and analyze the influence of waves on the thrust and torque of propeller. The results show that time history curves of thrust and torque oscillate under the influence of waves. The disturbance of free surface and the oscillation amplitude of time history curves increase with the decrease of immersion depth and advance coefficient. Compared with the calm water condition, the average thrust and torque of propeller in waves are reduced when the immersion depth and advance coefficient are the same. The computational results are in good agreement with the experimental data.

Key words： wave; propeller; thrust; torque; hydrodynamic performance
