Abstract

The use of energy-saving devices is the most effective method for decreasing CO2 emissions, which is an increasingly concerning environmental issue. The asymmetric pre-swirl stator has been developed as an energy-saving device and has been successfully applied to various types of vessels. In the present study, a flexible material was applied to an asymmetric pre-swirl stator to determine the variation in the flow around stator and its efficiency. A fluid–structure interaction (FSI) analysis system was developed using the Star-CCM+ (fluid) and the Abaqus (structure). The proposed analysis system was validated by comparing the experimental results using a flexible plate in a flowing fluid. The flexible stator was applied to a 3,600 TEU KRISO Container Ship to determine the improvement in its performance compared to the previous optimum value achieved with a rigid stator. Although this application was conducted on a model scale and the deformation was small, the results of the flexible stator indicated the possibility of not only increasing the efficiency but also decreasing the vortex risk around stator blade.

非对称预旋定子结构柔性对克里索集装箱船推进性能影响的可行性研究

使用节能装置是减少二氧化碳排放的最有效方法，这是一个越来越令人关注的环境问题。非对称预旋定子是一种节能装置，已成功应用于各种类型的容器。在本研究中，将柔性材料应用于不对称预旋定子，以确定定子周围流量的变化及其效率。使用Star CCM+（流体）和Abaqus（结构）开发了流体-结构相互作用（FSI）分析系统。通过比较在流动流体中使用柔性板的实验结果，验证了所提出的分析系统。将柔性定子应用于一艘3600标准箱KRISO集装箱船，以确定与之前使用刚性定子获得的最佳值相比，其性能的改善情况。尽管该应用是在模型尺度上进行的，并且变形很小，但柔性定子的结果表明，不仅可以提高效率，还可以降低定子叶片周围的涡流风险。
