Specific entry requirements
English 6 (or by other approved means with the equivalent proficiency level)Applicants enrolled in a programme at Chalmers where the course is included in the study programme are exempted from fulfilling the requirements above.
Course specific prerequisites
Mathematics (including mathematical statistics, numerical analysis and multi-variable calculus), Fluid mechanics.Aim
After finishing the course, the student will have basic professional knowledge in ship and propeller hydrodynamics and know the principles for designing an efficient hull and propeller. The student will have competence to set up, including the proper choice of tools and approximations, solve and analyse flow problems relating to hull resistance and propeller design.Learning outcomes (after completion of the course the student should be able to)
- Identify and discuss the resistance components, and their origin, of a ship hull;- Understand and discuss how different computational approaches for resistance can be used;
- Determine ship resistance by use of methods of different fidelity and critically evaluate results from different approaches;
- Understand and discuss the phenomena and design parameters that influence the propeller performance;
- Choose an appropriate propeller given necessary thrust and machinery characteristics;
- Understand and discuss the effects of interaction between hull and propulsor and how this affects the hull and propeller design;
- Understand and discuss the concept of scale similarity and scale effects;
- Apply the ITTC procedures to transform the hydrodynamic characteristics of a ship between model and full scale;
- Apply the ITTC procedures to determine propeller requirements from self propulsion tests.
Content
The course content can be classified into four different parts: (i) the origin, classification, and analysis of the different components of the resistance, (ii) the determination of hull and propeller performance through computational hydrodynamics, experiments in towing basins, or by empirical consideration, and (iii) the principles of hull design and tools to improve the efficiency of the design, and (iv) the principles of propeller design and tools to improve the efficiency of the design. Practical assignments using modern commercial software as well as towing tests results are used to exemplify the theoretical content of the course.Ship and propeller hydrodynamics

Organisation
Teaching is in the form of lectures and computer assignments.Literature

Examination including compulsory elements
Part A: Passed computer assignments, and seminar discussion on computer assignment results.Part B: Written exam.
The final grade is determined based on the results of the written exam and from bonus points gathered in the computer assignments.
The course examiner may assess individual students in other ways than what is stated above if there are special reasons for doing so, for example if a student has a decision from Chalmers on educational support due to disability.
