本研究主要是利用計算流體動力學方法探討巨型船舶推進螺旋槳葉片(簡稱俥葉)水下運動之流場數值模擬與分析，於受損時對於船舶航行效率的影響性以及對航運公司企業營運成本的衝擊性，另以高速推進之空泡激化器參數對其空化特性的影響與螺槳流場分佈變化與非線性物理現象機制，透過計算流體動力學方式，分析在不同航速下所造成之艉流分佈情形等各參數對行進間之船體水下運動之變化。本文研究除利用文字陳述螺旋槳原理作用，及在巨型船舶實務上受損原因及檢查維修方法、防止受損因應對策外，主要的實驗方法是藉由受損的螺槳葉片採電腦軟體方式模擬分析形成動態評估對船舶航行設備的影響及正確評估再生修理的可行性，並以此依據採取施工的方式使其恢復螺槳的功能性，以降低公司企業的經營成本損失。本文採用模擬分析為實際船舶螺旋槳幾何形體，利用計算流體力學方式進行模擬計算與分析，找出最佳應用化辦法以利選擇螺旋槳的修理方式或是採購新品更新方式的決定，以期能快速恢復船舶推進螺旋槳正常的功能性，為航運公司帶來節約成本的競爭優勢，以及就全球環境保護及生態而言達到節能減碳的目的，同時降低船舶海上碰撞及汙染風險為全球航運帶來完美的安全管理，以提供未來巨型船舶設計與改善減少噪訊與阻力之可行性。

This study mainly uses the computational fluid dynamics method to explore the numerical simulation and analysis of the flow field of the underwater motion of the giant ship propulsion propeller blades, the impact on the navigation efficiency of the ship and the operating cost of the shipping company. Impact, the effect of high-speed propellant cavitation intensifiers on its cavitation characteristics and propeller flow field distribution changes and nonlinear physical phenomena, through computational fluid dynamics, analysis at different speeds Variations of turbulent distribution and other parameters on the underwater motion of the hull during travel.
In this thesis, in addition to using the text to explain the role of the propeller principle, and the reasons for damage to the giant vessel practice, inspection and maintenance methods, and prevention of damage countermeasures, the main experimental method is to simulate and analyze the computer software by using damaged propeller blades. Forming the dynamic assessment of the impact on the ship's navigation equipment and the correct assessment of the feasibility of regenerative repair, and based on the construction method to restore the functionality of the propeller, to reduce the company's operating cost loss.
In this thesis, the simulation analysis is used for the actual ship propeller geometry, using computational fluid dynamics to carry out simulation calculation and analysis, to find the best application method to choose the propeller repair method or to purchase new product update method, to recover the ship quickly. Promote the normal functionality of the propeller, bring cost-saving competitive advantages to shipping companies, and achieve energy conservation and carbon reduction in terms of global environmental protection and ecology, while reducing the risk of marine collision and pollution, bringing perfect safety to global shipping. Management to provide future giant ship design and improve the feasibility of reducing noise and resistance.
