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.

Learning outcomes (after completion of the course the student should be able to)

After finishing the course, the student will have professional knowledge in ship hydrodynamics and know the principles for designing an efficient hull. 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.

The student should be able to:

- Identify and discuss the resistance components, and their origin, of a ship hull;
- Understand and discuss the concept of scale similarity;
- Use the ITTC procedures to transform the hydrodynamic characteristics of a ship between model and full scale;
- Understand and discuss how different computational approaches for resistance can be used;
- Critically evaluate results from different computational approaches;
- Determine ship resistance by use of potential flow methods;
- Determine ship resistance by use of RANS methods;
- Determine ship resistance by use of empirical methods;
- Understand and discuss the effects of interaction between hull and propulsor and how this affects the hull design;
- Evaluate how different design changes of the hull will affect the resistance.

Content

The course content can be classified into three different parts: (i) the origin, classification, and analysis of the different components of the resistance, (ii) the determination of resistance components 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. Practical assignments using modern commercial software as well as towing tests results are used to exemplify the theoretical content of the course.

Resistance components
- Basic equations and principles in ship hydrodynamics
