| 摘 要： | 该文研究了静水中动力定位系统推进器的桨-船干扰问题。首先对动力定位系统推进器桨-船干扰的影响因素进行分析,如前桨尾流冲击后桨所造成的桨-桨干扰、柯安达效应以及摩擦损失造成的桨-船干扰等,而后利用数值模拟方法和模型试验重点对推进器方位角的变化所造成的推进器桨-船干扰分析研究。经对比分析,动力定位推进系统中桨-船干扰可造成44%的推力损失,是动力定位推进器安装布置不可忽略的因素。该文的研究对提高动力定位推进系统效率,加强动力定位能力具有重要的意义。

| Abstract: | Based on CFD simulation and dynamic positioning system model test of a semi-submersible platform,some main factors causing propeller-hull interaction will be studied in this paper,such as the effect of Coanda effect and friction loss.The main work of this article is to discuss the change of azimuth angle how to influence the hydrodynamic characteristics of the thrusters.According to the results,the loss due to propeller-hull interaction could result in more than 40% loss of the thrust,so it’s necessary to carry out research in propeller-hull interaction so as to enhance the efficiency and capability of DPS. |
