Course: Resistance and Propulsion

Master Naval Architecture and Ocean Engineering

In this module, students will learn the physical fundamentals of ships resistance in a two-phase flow as well as to evaluate the thrust generation by a variety of propulsion organs with a focus on propellers. By gaining knowledge about the effective principles of propellers and the interaction with ship hull and the machineries, students are enabled to develop and assess propulsion concept. Competences are obtained to work interdisciplinary with experts from related fields such as hydrodynamic ship hull optimization, propeller development and ship main machineries in order to optimize the propulsion system under given boundaries. In addition, students will be qualified to interpret results from CFD calculations and rate enhancement measures of propulsions.

Lecture and seminar of this module in the course catalogue

  1. Repetition of fundamentals of fluid dynamics, boundary layer
  2. Resistance: friction-, pressure caused
  3. Wave energy
  4. Similarity law
  5. Method to extrapolate experimental data: Froude, Form-Factor-Method, ITTC
  6. Influence of ship parameters on ship resistance
  7. Downstream: reasons, distribution, effects, scale effects
  8. Suction: reasons, impact on propulsion efficiency, scale effects
  9. Propeller, -parameter, theory, propeller design, -optimization
  10. Interaction between ship - propeller- maschinaries.
  11. Measures to increase propulsion efficiency

The following topics will be covered in the seminars accompanying the lectures:

  • Fundamentals of ship drag/power prediction, proportions, similarity laws
  • Resistance and propulsion power estimation in design according to different prediction methods
  • CFD based wave resistance prediction as basis for ship hull form evaluation
  • Propeller design according to different optimization criteria
  • Wake: propeller inflow in the wake field
  • Model tests and transfer of results to full-scale: performance prediction

After consultation with the students, seminars are held on individual topics, which take several hours due to the complexity or the tools to be used.


To deepen the acquired knowledge, homework will be handed out, which must be worked on. The recognition of the solutions is a prerequisite for admission to the examination.
