Ship Effective Wake Investigation by using CFD methods

船体后的尾迹对螺旋桨和舵的性能有很大影响。CFD**模拟可以很容易地提供裸露船体后面详细的标称尾迹分布。然而，包括船体和螺旋桨相互作用在内的**有效尾迹更难预测。建议的**项目侧重于使用简化的和详细的**方法来预测船模的有效尾迹，目的是量化两种方法在精度上的差异。该项目将**最终决定哪种方法对船舶和螺旋桨设计最可靠。拟议的项目**解决了VARD Marine在提高燃油效率和降低噪音以**保护环境方面的关键具体问题。它还将使VARD能够进一步支持加拿大造船战略和**加拿大在船舶设计和技术方面的全球竞争力，这最终将使加拿大**经济受益。

The wake behind a ship hull significantly influences the performance of the propeller and rudder. CFD**simulation can readily provide a detailed nominal wake distribution behind the bare hull. However, the**effective wake, including the interaction of the hull and propeller, is more challenging to predict. The proposed**project focuses on the prediction of effective wake for a ship model by using the simplified and detailed**methods with the objective to quantify the differences in accuracy of the two methods. The project will**ultimately determine which approach is most reliable for ship and propeller design. The proposed project**addresses VARD Marine's specific problem critical in improving fuel efficiency and noise reduction for**environmental protection. It will also enable VARD to further support the Canadian Shipbuilding Strategy and**Canada's global competitiveness in ship design and technology, which will ultimately benefit the Canadian**economy.
