Ship Effective Wake Investigation by using CFD methods

船体尾流对螺旋桨和舵的性能影响很大。CFD**模拟可以很容易地提供一个详细的裸船体后的标称尾流分布。然而，有效尾流（包括船体和螺旋桨的相互作用）的预测更具挑战性。提出的**项目重点研究船舶模型有效尾流的预测，采用简化和细化的**方法，目的是量化两种方法在精度上的差异。该项目将最终确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问题。它还将使VARD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，这将最终使加拿大经济受益。

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.
