Course objectives:
Understanding the design principles of an efficient hull of a high-speed craft from a resistance point of view. Ability to set up a problem and use of properly selected tools and methods, solving and analyzing the flow around the ship hull in order to determine the total resistance of the ship. Understanding the methods of predicting the total resistance and the dynamic stability of single and multi-hull high-speed crafts.
Student responsibilities:
Grading and evaluation of student work over the course of instruction and at a final exam:
Project assignment, oral exam.
Methods of monitoring quality that ensure acquisition of exit competences:
Attending lectures and excercises, accomplishing project, oral exam.
Upon successful completion of the course, students will be able to (learning outcomes):
Analyze the flow phenomena around the ship hull. Identify the different resistance components of single and multi-hull high-speed crafts and their origin. Compare different methods to assess the resistance of high-speed crafts in order to select the most favourable method for the particular problem. Critically evaluate the results of different methods for particular example (project). Analyze the dependence between resistance and propulsion of high-speed crafts. Choose a type of propulsor for a specific project. Investigate the influence of variation of geometric hull features on the total resistance of the ship. Evaluate the dynamic stability, added resistance in waves and maneuverability of high-speed crafts.
